AB  - Abstract: Polyphenols present in different plant cell organelles increase the resistance of plants to various types of environmental
stresses. We investigated the possibility of increasing the content of bioactive compounds in the seed of yellow
soybean variety Laura. The soybean was treated during vegetation with five products based on plant extracts, on the
assumption of enrichment of plants with various nutrients. Soybean flour extracts were screened spectrophotometrically
for total phenolic content and antioxidant activity. The antioxidant activity was evaluated using three methods. The content
of phenolic acids was determined by HPLC, and the raw protein content was estimated by the Kjeldahl method. Depending
on the treatment, variations in the quantity of individual phenolic acids with up to 90% higher concentration as compared
to the control were observed. Controlled usage of certain plant extracts can increase the concentration of the target group of
bioactive compounds in the samples. The synergistic effect of proteins and phenolic compounds on the antioxidant activity
of extracts was detected. The results of this study are not only important from the aspect of plant resistance to various types
of stress, but also when considering soybean as a functional food.

AB  - Chitosan and its derivatives have been reported as a promising alternative for control of postharvest fungal pathogens. The objective of this study was to evaluate in vitro and in situ antifungal activity of chitosan against Alternaria alternata and Colletotrichum gloeosporioides isolated from decayed apple fruits. The fungi were tested in vitro using PDA medium with three concentrations of chitosan (1, 2 and 3 mg/ml). Fungal growth of the test pathogens was significantly affected by all chitosan doses (P lt 0.05) after 7 days of incubation at 25°C. Water solution of 3 mg/ml of chitosan inhibited completely the conidial germination of A. alternata and C. gloeosporioides after 18 h incubation at 25°C. The results obtained from biocontrol assay indicate that the inhibition of postharvest decay of A. alternata and C. gloeosporioides was significantly influenced by chitosan concentrations. Disease incidence in chitosan-treated fruit after 7 days incubation at 25°C was significantly lower than in the positive control for both fungi tested (P lt 0.05). A. alternata and C. gloeosporioides used in this study were progressively inhibited in vitro and in situ with increasing concentrations of chitosan from 1 to 3 mg/ml.

AB  - The aim of the study was to investigate and compare several extraction protocols like 1) high-power ultrasound probe assisted solvent extraction; 2) microwave assisted solvent extraction; 3) direct acid hydrolysis; 4) direct alkali hydrolysis, and 5) two step extraction consisting of ultrasound or microwave assisted solvent extraction followed by alkaline and acid hydrolysis in terms of efficiency of the extraction of phenolic acids from the yellow soybean seed variety Laura. These extracts were screened for their total phenol content (TPC), and for their antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl radical scavenging (DPPH) assay, as well as on content of some individual phenolic acids. It appeared that the acetone containing mixtures gave much higher TPC than methanol containing ones, but the presence of acid in the methanol solvent significantly improved the extraction of phenolic compounds. To further improve the extraction, an ultrasound lab-scale probe at 20 kHz was used, with 15 and 30% of the maximum amplitude, and the extraction time was varied from 2 to 15 min. Microwave assisted extraction was performed varying the temperature from 55 to 85 degrees C, microwave power from 25 to 100 W and extraction time from 2 to 10 min. Changes in the content of six phenolic acids were examined: gallic, trans cinnamic, chlorogenic, caffeic, p-coumaric and ferulic acid. The separation and quantification of phenolic acids was accomplished by high-performance liquid chromatography-diode array detection (DAD) procedure. The results suggested that microwaves contributed to more efficient extraction of phenolic acids from the seed of yellow soybean. The amount of phenolic acids varied from 65.52 mu g/g of dry matter (d.m.) for caffeic acid, to 581.84 mu g/g d.m. for p-coumaric acid. Both, ultrasound and microwaves contributed to more efficient extraction of total phenol compounds and enhanced antioxidant activity of soybean seed extracts. TPC varied from 12.48 to 18.77 mg GAE/g d.m. and antioxidant activity varied from 244.58 to 345.21 mu mol TROLOX eq/g d.m.

AB  - During the 80s it was considered that a new era in agriculture has begun with the manipulation of plant growth through the use of synthetic regulators. Growth regulators (GR) have found their application in different crops (cereals, tobacco, potato, bananas, coffee, cotton, oilseed rape) and plantations (fruit and citrus orchards and vineyards). In order to examine the influence of GR on the growth of plants, i.e. their lateral branches, the trials were conducted in tobacco, winter wheat and oilseed rape fields, with the aim to evaluate the effects of growth regulators. Maleic hydrazide potassium and different concentrationsof butralin were applied in tobacco, while tebuconazole was applied in oilseed rape and ethephon in wheat. Analysis of the results has shown that the application of GR has had an effect on the growth of lateral tobacco shoots and oilseed rape and wheat plants. Statistically signifficant differences between the control and treated plants have been determined for all of the assessed rates of growth regulators. The effects were more pronounced on the length of lateral shoots in the upper nodes of tobacco, while in oilseed rape a higher efficiency was registered following fall treatments.
AB  - Osamdesetih godina prošlog veka smatralo se da manipulacija rastom biljaka zasnovana na korišćenju sintetičkih regulatora, predstavlja početak nove ere u poljoprivrednoj praksi.

abstract = "During the 80s it was considered that a new era in agriculture has begun with the manipulation of plant growth through the use of synthetic regulators. Growth regulators (GR) have found their application in different crops (cereals, tobacco, potato, bananas, coffee, cotton, oilseed rape) and plantations (fruit and citrus orchards and vineyards). In order to examine the influence of GR on the growth of plants, i.e. their lateral branches, the trials were conducted in tobacco, winter wheat and oilseed rape fields, with the aim to evaluate the effects of growth regulators. Maleic hydrazide potassium and different concentrationsof butralin were applied in tobacco, while tebuconazole was applied in oilseed rape and ethephon in wheat. Analysis of the results has shown that the application of GR has had an effect on the growth of lateral tobacco shoots and oilseed rape and wheat plants. Statistically signifficant differences between the control and treated plants have been determined for all of the assessed rates of growth regulators. The effects were more pronounced on the length of lateral shoots in the upper nodes of tobacco, while in oilseed rape a higher efficiency was registered following fall treatments., Osamdesetih godina prošlog veka smatralo se da manipulacija rastom biljaka zasnovana na korišćenju sintetičkih regulatora, predstavlja početak nove ere u poljoprivrednoj praksi. Regulatori rasta (RR) su našli primenu u različitim usevima (strna žita, duvan, krompir, banana, kafa, pamuk, uljana repica) i zasadima (voće, vinova loza, citrusi).

AB  - The aim of the study was to find the optimal operational and process parameters for the enzymatic hydrolysis of wheat gluten in a batch stirred bioreactor regarding both degree of hydrolysis and antioxidant capacity of the obtained hydrolysates. It appeared that impeller geometry and agitation speed influenced the mass transfer resulting in enhanced gluten hydrolysis. The highest initial reaction rate (0.83 0.02 min(-1)) and degree of hydrolysis (30.47%) were achieved with the pitched four-bladed impeller and agitation speed of 350-450 rpm, conditions which provided proper balance between requirements for adequate mass/heat transfer and low shear stress. The impact of other process conditions including gluten concentration, temperature, pH and enzyme gluten (E/S) ratio on the enzymatic reaction was investigated by applying a Box-Behnken experimental design from the viewpoint of the degree of hydrolysis (DH) and antioxidant activity. Three models obtained allowed calculation of the hydrolysis degree, and both 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulpfonic acid) radical scavenging activity from a given set of reaction conditions with good predictability. The statistical analysis showed that each variable had a significant effect on degree of hydrolysis and the antioxidant capacity of both tested systems. Hydrolysis up to around DH 15% improved DPPH radical scavenging activity, while excessive hydrolysis worsened it. The ABTS activity of the hydrolysates was not associated with the DPPH activity nor with the DH, revealing that it was not possible to fulfill all desirable quality requirements (maximum degree of hydrolysis and protein yield, maximum DPPH and ABTS scavenging activities) by using the Same reaction conditions. Overall, the study might contribute to approve wheat gluten, a by-product of wheat starch industry, as an accessible and cheap source of bioactive compounds for the development of novel nutraceuticals, cosmetics and drugs.

AB  - Background: Chemical composition of soybean grain may be modified by application of foliar fertilizers. The aim of this study was to test the effect of different organo-mineral foliar fertilizers: Zlatno inje, Bioplant Flora, Algaren BZn, Zircon, as well as plant growth regulator Epin Extra, on potential availability of mineral elements (Mg, Fe, Mn and Zn) from grain of three commercial soybean varieties: ZP-015, Nena and Laura (variety lacking in Kunitz trypsin inhibitor). In addition, phytate (Phy) and beta-carotene contents were determined. Results: ZP-015 achieved the highest P, Mg, Fe, Mn and beta-carotene contents. Laura had the highest Phy level, which might reflect the diminished availability of nutrients from grain. Compared to control, most of the applied fertilizers increased beta-carotene and decreased Mn content in all three soybean varieties. Increase in beta-carotene content was followed by increase in Fe content, mainly in grains with larger weight, as a part of improved yielding potential. Conclusions: Positive effect of Zircon application was evident on increased grain weight, and beta-carotene and Fe content. These parameters together with the lowest values found for Phy/beta-carotene and Phy/Mg ratios may explain the enhanced Mg and Fe bioavailability. On the other hand, positive effects of Epin Extra were mostly reflected by a decrease of Phy and an increase in Fe and Mn, thus becoming more bio-available. Accordingly, the organo-mineral foliar fertilizers based mainly on phenolic acids (Zircon) and bioregulator (Epin Extra) are to be recommended for soybean fortification.

AB  - One way of fast and effective impact on yield, pomological and biochemical properties of apple fruits is foliar fertilization. Thus, the fruit efficiently recharge poorly mobile secondary and micronutrients, and so the plant protects against environmental stress in sensitive developmental stages. The last hypothesis we checked during the second part of the growing seasons of 2014, which were characteristic of abundant precipitation during the first part of the season. The experiment was set in 19th May 2014, in the 18 years old apple (Malus domestica L. cv. 'Idared') orchard by a block system (10-12 trees per treatment), at a density of 1300 trees per ha. Treatments (19th May and 3rd Jun of 2014) per blocks were: control, 'Eco-Fus' (45 ml; based on algae extract), 'Vegard' (48 ml), 'Calbit-C' (20 ml), 'Zircon' (2,4 ml), 'Cropmax' (40 ml), (all based on plant extracts), 'Chitosan' (8 ml; based on shellfish extract), all dissolved in 8 l of water. The samples for biochemical analysis (determination the pH value and coefficient of refraction of the fruit extracts) were taken on 19th May, 3rd June, 2nd July, and on 9th September, when estimated yield. The yield was estimated by counting fruits on the tree in each block-treatment, followed by sampling a large number of fruits (20 and over), measuring their weight and multiplication, in order to estimate the yield per tree and per ha. All of the tested fertilizers in the given conditions are significantly higher estimated yield than in the control plants. Estimated yield of treated plants increased from +28.93% ('Calbit-C' fertilizer) to +253.26% ('Chitosan' fertilizer) per tree, ie. from +26.52% ('Calbit-C' fertilizer) to +253.27% ('Chitosan' fertilizer) per hectare, all relative to control. The average fruit weight was not significantly varied between treatments (200-230 g), but the number of fruits per tree is very influenced by the type of fertilizer, particularly in the case of 'Chitosan' fertilizer. It should be noted that the type of fertilizer affects the coefficient of refraction of the fruit extracts, particularly in the case of 'Eco-Fus' fertilizer.

Tretmani po blokovima su bili: Kontrola (bez tretmana), 'Eco-Fus' (đubrivo na bazi ekstrakta algi), 'Ve­gard', 'Calbit-C', 'Zircon', 'Cropmax', (sva đubriva na bazi biljnih ekstrakata), 'Chitosan' (homeopatski proizvod na bazi ekstrakta morskih školjki), pri čemu su đubriva rastvarana u vodi. Uzorci za biohemijsku analizu (određivanje pH vrednosti i koeficijenta refrakcije ekstrakta pulpe ploda jabuke) uzimani su četiri puta, sve do procene prinosa. Prinos je procenjivan brojanjem plodova na stablima u svakom blok-tretmanu, posle čega je sledilo uzorkovanje većeg broja plodova po blok-tretmanu, merenje težina plodova i multiplikacija težine sa brojem plodova po stablu, radi procene prinosa po stablu i po standardnoj površini (ha). Sva testirana đubriva u datim agroekološkim uslovima značajno su uvećala prinos jabuka odnosno kontrole (od +28.93% ('Calbit-C'), do +253.26% ('Chitosan') po stablu, tj. (od +26.52% ('Calbit-C'), do +253.27% ('Chitosan') po standardnoj površini (ha). Srednja masa plodova nije značajnije varirala između tretmana, ali broj plodova po stablu jeste, zavisno od tretmana, posebno u slučaju đubriva 'Chitosan'.

AB  - As photosynthesis is the basic process during which light energy is absorbed and converted into organic matter, the importance of the plant pigment chlorophyll (a and b forms) as an intermediary in transformation of the absorbed solar energy and its activity in the process of photosynthesis and synthesis of organic substances in plants are crucial. Therefore, this paper provides an overview of methods for monitoring the optical activity of chlorophyll molecules and methods (non-destructive and destructive) for quantification of chlorophyll in plants. These methods are used to estimate the effects of different stress factors (abiotic, biotic and xenobiotic) on the efficiency of photosynthesis and bioproductivity, aiming to assess the impact that these limiting factors have on the yield of various cultivars. Also, those methods for analysis of chlorophyll optical activity and/or content are appropriate for assessing the reaction of weed species to different agricultural practices (mineral nutrition, treatment by herbicides, etc.) and studies of different aspects of weed ecophysiology and their influence on crop harvest.
AB  - Kako je proces fotosinteze osnovni proces tokom kojeg se svetlosna energija apsorbuje i konvertuje u organsku materiju, ključni je značaj postojanja biljnog pigmenta hlorofila (a i b forma) kao posrednika u transformaciji apsorbovane svetlosne energije i njegove aktivnosti u procesu fotosinteze i sinteze organskih materija kod biljaka. Stoga je u radu dat pregled metoda za praćenje optičke aktivnosti molekula hlorofila, kao i metoda (nedestruktivnih i destruktivnih) kvantifikacije hlorofila u biljkama. Ove metode se primenjuju u proceni uticaja različitih stresnih faktora (abiotskih, biotskih i ksenobiotskih) na efikasnost fotosinteze i bioproduktivnost biljaka, sa ciljem procenjivanja uticaja koji ovi ograničavajući faktori imaju na prinos useva. Takođe, pomenute metode za analizu optičke aktivnosti i/ili sadržaja hlorofila su odgovarajuće i za procenu reakcije korova na različite poljoprivredne prakse (mineralna ishrana, primena herbicida i sl.) i ispitivanje različitih aspekata ekofiziologije korova i procenu njihovog uticaja na prinos useva.

AB  - Nowadays, both worldwide and in Serbia, for weed eradication in orchards mostly herbicides based on glyphosate, glufosinate-ammonium, diquat and others are used. Intensive glyphosate application has led to the development of resistant weed species, which has consequently resulted in a decrease in its effectiveness. In our country, areas under orchards amount to 224.000 hectares, which certainly points to a significant herbicide use and a possibility that weed resistant populations have developed. For this reason, seeds of several weed species from areas where glyphosate has been intensively used for years were collected (localities: Inđija, Brestovac, Šabac, Vršac, Sombor, Glogonjski Rit, Padinska Skela and Surčin). Plants were grown in controlled conditions and in the open field. Plant material was then crushed using liquid nitrogen, and the extraction of shikimic acid was performed using hydrochloric acid (1 g of plant material + 5 ml 1M HCl). 24 hours later the amount of shikimic acid was detected using high-pressure liquid chromatography. The analysis of the obtained results showed that species Amaranthus retroflexus (loc. Šabac), Abutilon teophrasti (loc. Brestovac) and wild Helianthus annuus (loc. G. Rit) have developed a certain degree of glyphosate resistance.
AB  - Danas, u Svetu i kod nas, za suzbijanje korova u voćnjacima najviše se koriste herbicidi na bazi glifosata, glufosinat-amonijuma, dikvata i drugi. Intenzivna primena glifosata uticala je na pojavu rezistentnih korovskih vrsta što za posledicu ima smanjenu efikasnost. U našoj zemlji površine pod voćnim zasadima iznose 224 hiljade hektara što svakako ukazuje na veliku upotrebu herbicida i mogućnost da je došlo do razvoja rezistentnih populacija korova. Zbog toga su sakupljana semena nekoliko korovskih vrsta sa površina gde je bila višegodišnja intenzivna primena glifosata u voćnjacima (Inđija, Brestovac, Šabac, Vršac, Sombor, Glogonjski Rit, Padinska Skela, Kosančić i Surčin). Biljke su gajene u kontrolisanim uslovima i na otvorenom polju.

Nakon 24 h očitavan je sadržaj šikiminske kiseline na tečnom hromatografu (HPLC). Analiza dobijenih rezultata je pokazala da su vrste Amaranthus retroflexus (lok. Šabac), Abutilon theophrasti (lok.

AB  - Leaf canopy manipulation by shading (irrelevant from the plants was treated with herbicide sulfosate or not) of maize plants raised in controlled environment, did not caused large changes in partitioning of dry-mass in plant. But inhibition of dry-matter and growth of maize plants caused by sulfosate treatment is bigger in unshaded (S) in relation to shaded (Sh) plants. Our opinion is that differences caused by functional-compensation processes, before viewed in other types of manipulation of source-sink relationship in plant. Inhibition of parameters of Chla fluorescencije and photosynthesis, caused by herbicide sulfosate, beginning in 6th day of trial, but decay of maize leaf photosynthetic function is so rapidly. Meanwhile in control plants that parameters on the end of trial is larger in shaded (Sh) relative to unshaded (S) plants. We interpreted that result also as functional-compensation processes. In maize plants raised in the field conditions under full day-light and then transfered in the shade (were they acclimatized), we noticed large inhibitions of growth, accumulation of dry-matter and their allocation in root and leaves with considerable increase of stem dry-mater and also early decrease of value of RWC parameter of leaves water regime under treatment of herbicide sulfosate. Besides that treatment of sulfosate in shaded plants caused significant decrease of all parameters of photosynthesis and Chla fluorescence. That caused early degradation of Chla and Chl b photosynthetic pigments, and degradation of carotenoids only at the end of trial (according to unchanged values of NPQ parameter of leaf photoprotektion) in shaded and sulfosate treated maize plants. Conclusion is that antenic function of photosynthesis was not destroyed by sulfosate action. Accordingly that in shaded maize plants the main part of inhibitory and degradative processes caused by herbicide sulfosate to mediate by inhibition of functions and growth of root and also by inhibition of water regime of leaves. Shading of herbicide sulfosate treated maize plants, raised in controled environment is largely different in comparison to shaded and sulfosate-treated maize plants raised in the field. We interpreted that differences with fact that shading of plants raised in controlled environment is not complete and it is more shorter than in field plants, and this results we interpreted as functional-compensation processes. But in field plants shading is so longer before treatment, and in this plants raised so called phenotype of 'shade plants', particularly sensitive to inhibitory action of sulfosate. And as conclusion we stated that longevity and completeness of shading is very influential factor to inhibitory action of sulfosate on maize plants. That testify of importance of 'source-sink' relationship in this particularly case.
AB  - Manipulacija statusom lisnog pokrova putem zasenjivanja (nezavisno od toga da li su tretirane ili ne herbicidom sulfosatom) biljaka kukuruza raslih u kontrolisanim uslovima, ne dovodi do značajnijih izmena u preraspodeli suve mase. Međutim, inhibicija akumulacije suve mase i rastenja biljaka kukuruza usled tretmana sulfosatom znatno je veća kod nezasenjenih (S) odnosno zasenjenih (Sh) biljaka. Smatramo da su ove razlike uslovljene funkcionalno kompenzacionim procesima, ranije primećenim kod drugih vidova manipulacija 'proizvođač-potrošač' odnosa u biljci.

Kod biljaka kukuruza raslih u polju, pri punoj dnevnoj svetlosti, pa prenetih u senku (gde su aklimatizovane), zapažamo znatnu inhibiciju rastenja, akumulacije ukupne suve mase i njene alokacije prema korenu i listovima, uz znatno povećanje udeone suve mase stabla i rano smanjenje vrednosti RWC parametra vodnog režima listova, pri tretmanu herbicidom sulfosatom. Pored toga tretman sulfosatom dovodi kod zasenjenih biljaka i do značajnog sniženja svih parametara fotosinteze i fluorescencije Chla.

Prema tome, kod zasenjenih biljaka kukuruza većina inhibitornih i degradativnih procesa uzrokovanih dejstvom sulfosata posredovano je inhibicijom rastenja i funkcije korena, kao inhibicijom vodnog režima listova.

To tumačimo time da je kod kontrolisanih biljaka zasenjivanje bilo delimično i znatno kraće, pa se nastale promene mogu smatrati procesima kompenzacije, dok je kod biljaka raslih u uslovima polja zasenjivanje bilo dugotrajnije pre samog tretmana, pa se nastali fenotip 'biljaka senke' pokazao veoma osetljivim na inhibitorno dejstvo sulfosata.

abstract = "Leaf canopy manipulation by shading (irrelevant from the plants was treated with herbicide sulfosate or not) of maize plants raised in controlled environment, did not caused large changes in partitioning of dry-mass in plant. But inhibition of dry-matter and growth of maize plants caused by sulfosate treatment is bigger in unshaded (S) in relation to shaded (Sh) plants. Our opinion is that differences caused by functional-compensation processes, before viewed in other types of manipulation of source-sink relationship in plant. Inhibition of parameters of Chla fluorescencije and photosynthesis, caused by herbicide sulfosate, beginning in 6th day of trial, but decay of maize leaf photosynthetic function is so rapidly. Meanwhile in control plants that parameters on the end of trial is larger in shaded (Sh) relative to unshaded (S) plants. We interpreted that result also as functional-compensation processes. In maize plants raised in the field conditions under full day-light and then transfered in the shade (were they acclimatized), we noticed large inhibitions of growth, accumulation of dry-matter and their allocation in root and leaves with considerable increase of stem dry-mater and also early decrease of value of RWC parameter of leaves water regime under treatment of herbicide sulfosate. Besides that treatment of sulfosate in shaded plants caused significant decrease of all parameters of photosynthesis and Chla fluorescence. That caused early degradation of Chla and Chl b photosynthetic pigments, and degradation of carotenoids only at the end of trial (according to unchanged values of NPQ parameter of leaf photoprotektion) in shaded and sulfosate treated maize plants. Conclusion is that antenic function of photosynthesis was not destroyed by sulfosate action. Accordingly that in shaded maize plants the main part of inhibitory and degradative processes caused by herbicide sulfosate to mediate by inhibition of functions and growth of root and also by inhibition of water regime of leaves. Shading of herbicide sulfosate treated maize plants, raised in controled environment is largely different in comparison to shaded and sulfosate-treated maize plants raised in the field. We interpreted that differences with fact that shading of plants raised in controlled environment is not complete and it is more shorter than in field plants, and this results we interpreted as functional-compensation processes. But in field plants shading is so longer before treatment, and in this plants raised so called phenotype of 'shade plants', particularly sensitive to inhibitory action of sulfosate. And as conclusion we stated that longevity and completeness of shading is very influential factor to inhibitory action of sulfosate on maize plants. That testify of importance of 'source-sink' relationship in this particularly case., Manipulacija statusom lisnog pokrova putem zasenjivanja (nezavisno od toga da li su tretirane ili ne herbicidom sulfosatom) biljaka kukuruza raslih u kontrolisanim uslovima, ne dovodi do značajnijih izmena u preraspodeli suve mase.

AB  - Chlorophyll is a green pigment important in photosynthesis. By monitoring chlorophyll amount we learn about productivity of photosynthesis. Many herbicides with different modes of action affect the amount of chlorophyll in plant tissue. In our study we examined the amount of chlorophyll in corn plants after application of glyphosate trimesium (sulfosate). We used a non-destructive method: SPAD reading and chlorophyll a fluorescence, and a destructive method: extraction of chlorophyll with dimethil formamide and methanol. Our results show that based on amount of photosynthesis pigments and chlorophyll fluorescence yield we can monitor the stress effect of herbicides on corn plants. Our results also show that we can differentiate between treated and non treated plants.

AB  - The effects of PAR and temperature on induction of Chl a fluorescence were observed on leaves of 20 plant species in their natural environments. Light affects the acceptor side of PS2. Temperature regulation of PS2 activity proceeds by affecting the RC and acceptor side of PS2. The impact of higher temperature can be attributed to greater fluidity of the thylakoid membranes. Photosynthetically active radiation and temperature under the given conditions are in highly significant positive correlation, so it is not clear whether this impact is due to individual or complementary mechanisms of PAR and/or temperature affecting photosynthetic processes in the thylakoid membranes. Also, it is not clear whether species specificity has any significance in the plant photosynthetic response to changes of PAR and temperature. Changes of PAR and temperature during induction of Chl a fluorescence do not affect Pindex, as a parameter of total photosynthesis.
AB  - Praćen je uticaj PAR i temperature na indukciju fluorescencije Chl a na listovima 20 biljnih vrsta u njihovom prirodnom okruženju. Svetlost deluje na akceptorsku stranu PS2. Regulacija aktivnosti PS2 temperaturom odvija se uticajem na RC i akceptorsku stranu PS2. Uticaj povišene temperature moguće je objasniti i povećanom fluidnošću tilakoidnih membrana. PAR i temperatura u datim uslovima nalaze se u visokoznačajnoj pozitivnoj korelaciji, tako da nije jasno da li se radi o posebnim ili komplementarnim mehanizmima dejstva PAR i/ili temperature na fotosintetske procese u tilakoidnim membranama. Takođe nije jasno da li specijska specifičnost ima neki značaj u fotosintetskoj reakciji biljaka na promene PAR i temperature. U ovim procesima promene PAR i temperature ne utiču na Pindex, kao pokazatelj ukupne fotosinteze.

Changes of PAR and temperature during induction of Chl a fluorescence do not affect Pindex, as a parameter of total photosynthesis., Praćen je uticaj PAR i temperature na indukciju fluorescencije Chl a na listovima 20 biljnih vrsta u njihovom prirodnom okruženju. Svetlost deluje na akceptorsku stranu PS2. Regulacija aktivnosti PS2 temperaturom odvija se uticajem na RC i akceptorsku stranu PS2. Uticaj povišene temperature moguće je objasniti i povećanom fluidnošću tilakoidnih membrana. PAR i temperatura u datim uslovima nalaze se u visokoznačajnoj pozitivnoj korelaciji, tako da nije jasno da li se radi o posebnim ili komplementarnim mehanizmima dejstva PAR i/ili temperature na fotosintetske procese u tilakoidnim membranama. Takođe nije jasno da li specijska specifičnost ima neki značaj u fotosintetskoj reakciji biljaka na promene PAR i temperature. U ovim procesima promene PAR i temperature ne utiču na Pindex, kao pokazatelj ukupne fotosinteze.",

AB  - Effect of the herbicide sulphosate on the growth, accumulation and distribution of dry weight, photosynthesis and water regime in maize plants grown in controlled environment was investigated. The herbicide sulphosate was found to significantly lowered dry matter acumulation and slow down growth of maize plants. Dry weight accumulation, which ultimately determines growth, was found to correlate highly significantly with dry matter allocation to root and leaves, but this dependence was not unique. Under influence of sulphosate dry matter allocated from leaves to stem. That the phenomena result from a specific carbohydrate metabolism in stem of maize plants (not contain starch). The herbicide sulphosate significantly affect the status and functioning of the root and water regime of maize plants (lowered values of parameters Vr and RWC). Changes in photosynthesis and photosynthetic structures (degradation of photosynthetic pigments) under the effect of sulphosate precede changes in the water regime of leaves of maize plants. This effects must be seen as photoinhibition of photosynthesis with photooxydation of photosynthetic pigments (particularly Chla) under sulphosate-provoked stress. 'Light curves' of different parameters of Chla fluorescence (qP, Fv,/Fm,, Φ PS2) lowered under increased actinic light. ETR para-meter of photosynthesis had sigmoid dependence of PAR, like to kinetic of photosyntetic fixation of CO2. Parameters of Chla fluorescence and photosynthesis can be used to monitor and assess the volume of functional senescence of photosynthesis in maize leaves both in the control plants and those exposed to sulphosate-caused stress.
AB  - U radu se razmatra dejstvo herbicida sulfosata na rastenje, akumulaciju i preraspodelu suve mase, fotosintezu i vodni režim biljaka kukuruza, raslih u kontrolisanim uslovima. Herbicid sulfosat značajno umanjuje akumulaciju suve mase, usporava rastenje biljaka kukuruza i utiče na preraspodelu suve mase u biljci. Poslednji efekat verovatno je u vezi sa specifičnošću metabolizma ugljenih hidrata u stablu kukuruza. Akumulacija suve mase i rastenje kukuruza zavise od preraspodele suve mase u koren i listove, što bi bio jedan od uzroka fitotoksičnog dejstva sulfosata. Pored toga, sulfosat inhibira funkcije korena i vodni režim listova kukuruza. Ipak, najraniji efekat sulfosata jeste fotoinhibicija fotosinteze, za kojom sledi degradacija fotosintetskih pigmenata i struktura. Metoda fluorescencije Chla može se koristiti za in situ praćenje funkcionalnog starenja listova u stanju stresa, kao npr. pri dejstvu herbicida sulfosata.
