AB  - The environment protection, energy, and resources preservation are especially pronounced under present climate changes. In agriculture, these changes are recognised as drought, high temperatures, occurrence of stormy winds and hail. The aim of this study was to determine variations in seed morphology that are a result of different sowing dates in relation with agro- ecological conditions of maize (Zea mays L.) cultivation. The material used for the study encompassed three inbred lines (G1, G2, G3) sown every 10 d on five sowing dates (T1, T2, T3, T4, T5) starting from 1 April to 10 May, during 2 yr (Y1: 2018, Y2: 2019). The following physical properties of seeds were estimated: width (W), length (L), thickness (Tk), ratio of small (SF) to large fraction (LF) and grain yield (GY). The width was the highest in all three inbreeds on T4 (1.00, 1.03, 0.99 cm, respectively); T5 was the least favourable date for L (1.09, 1.12, 1.09 cm, respectively) while Tk was the lowest in G1 (0.51 cm) and G2 (0.51 cm) sown on T1. The most significant differences in the formation of physical properties occurred in seeds sown on T5 (p ≤ 0.05). The highest differences were observed in width between T5-T4 (-0.223 cm), in length between T5-T2 (-0.309 cm) and in thickness between T5-T3 (-0.129 cm). Later sowing dates favoured LF (85.2%) in comparison to SF (14.7%). Seed size variability participated with 50% in yield formation (R2 ≥ 0.5).

AB  - The uniform seed material is a prerequisite of stable yields. Therefore, the aim of the study was to observe variability of physiological seed traits depending on the classification of seeds by size and shape, and to determine advantages of large over small seed fractions. Three maize (Zea mays L.) hybrids (ZP 505, ZP 677, ZP 684), produced in two locations (Orahovo, Plavna), were classified into six fractions; small flat seed (SFS), medium small flat seed (MSFS), large flat seed (LFS), small round seed (SRS), medium small round seed (MSRS) and large round seed (LRS). Two laboratory treatments were applied on seed: TR1 (cold test) and TR2 (20/30 ºC). In both temperature treatments, the first evaluation was done after 72-h germination, and then every 24 h until 7th day. The highest total germination (G) was recorded for ZP 677 (93.7%), location Orahovo (94.9%), temperature TR2 (95.2%) and MSFS fraction (89.7%). The total proportion of factors in the variance for G was R2 = 0.694. Locations and genotypes predominantly affected the germination rate (GR), η = 0.338. Flat fraction seeds had more rapid emergence (> 90%) of seedlings than the round fraction seeds (> 85%). Round seeds were more susceptible and seed size had a greater effect on vigour than LRS, 70%. The partial effect of the fraction on G was not estimated (η = 0.037), but its cumulative effect with other factors was evident (Hybrid × Fraction, η = 0.070).

AB  - Buckwheat (Fagopyrum esculentum Moench.) seed, produced in three locations, was used in the present study. Seed was stored in paper, glass, wood and PVC packing materials under room temperature conditions (18 degrees C) for five years. The following parameters of seed quality were observed: viability, germination, dormancy and a 1000-seed weight. Standard laboratory methods were applied in the studies. The lowest viability after harvest was recorded in seeds stored in glass or PVC packing materials. All factors pointed to a great significance in the expression of viability, germination and seed weight maintenance. The highest value of germination (99%) was recorded in seeds produced in the location Karbulovo after two-year storage in the paper packing material. In the second year of storage, seed dormancy in paper packing material amounted to 0-0.1%. The seed weight changed during the storage period from 33.9 g to 24.4 g. The weight loss was the lowest in seeds stored in the paper packing material. The germination decline was slower in large than in small seeds. Obtained results indicate the importance of packing material for maintenance of seed qualitative traits. According to the gained results, seeds packed in paper packing material mostly retained their physiological and morphological traits.

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  - 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  - Deficiencies of mineral elements in human nutrition could be surpassed by crop fortification. One of the prevalent measures of fortification is foliar fertilization. The aim of this study was to determine the content and availability of the mineral nutrients Mg, Fe and Zn, together with phytate, as an anti-nutritive factor, and β-carotene as a promoter of mineral nutrient availability in grain of two soybean cultivars (Nena and Laura) treated with different non-standard foliar fertilizers (mainly based on plant extracts). Generally, a negative correlation between Fe and phytate indicated that factors which decrease phytate and increase β-carotene could be primarily responsible for Fe utilization by humans and animals. Zlatno inje (based on manure) had the highest impact on increasing the grain yield and decreasing the ratios between phytate and mineral elements in Nena grain, while for Laura, it was generally Zircon (based on an extract of Echinacea purpurea L), increasing also availability of mineral elements.

AB  - High-performance thin-layer chromatography (HPTLC) combined with image analysis and pattern recognition methods were used for fingerprinting of phenolic compounds present in seedlings of two maize genotypes ZP 434 (new generation hybrid, drought tolerant) and ZP 704 (older generation hybrid, drought sensitive) treated with different concentrations of 24-epibrassinolide. This is the first report of TLC chromatographic profile of phenolics' mixtures in maize seed extracts influenced by brassinosteroid phytohormones. Nine samples of shoot of seedlings for the whole concentration range of phytohormones (5.2 x 10(-7) -5.2 x 10(-15) M), one sample of root of seedlings treated with 5.2 x 10(-15) M 24-epibrassinolide, and the control samples of nontreated seedlings, for both genotypes, were analyzed. Phenolic profiles of root extracts indicate the absence of more polar compounds such as phenolic acids and glycosides present in shoot of seedlings. Also, hormones applied in higher concentrations have an inhibiting effect on the content of phenolics in ZP 434. Application of chemometric methods enables characterization of particular genotype of maize according to its phenolic profile.

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  - 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.

abstract = "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., 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.

AB  - Background: The 2,4-D (2,4-dichlorophenoxyacetic acid) is using as a growth regulator in tissue culture media. Maize seeds have poor ability to maintain germination rate in the long term. Objective: To examine the possible restorative effect of homeopathic 2,4-D potencies on maize seedlings originating from seeds damaged by accelerated aging. Methods: Seeds of four maize lines were subjected to accelerated aging stress treatment. Seed samples were treated with distilled water (control) and a range of potencies of 2,4-D: 3C, 3.75C, 4.5C, 5.25C and 6C. The germination capacity, fresh substance (FS) and length of root and shoot were determined. Hydrolysis and biosynthesis, GSH/GSSG ratio and redox capacity were calculated. Results: Induced seed aging decreased germination rate and growth of seedlings. 2,4-D potencies did not have a statistically significant effect on germination. However, there were statistically significant effects on FS production, root and shoot length and redox capacity. The 3C potency had the largest effect on the FS accumulation, 4.5C increased root and shoot length, compared to control (statistically significant). The GSH/GSSG ratio and the redox capacity were decreased by aging. The 3C and 4.5C potencies tended to reverse the GSH/GSSG ratio (statistically significant) in the root and shoot, (i.e., shifted the redox balance to the reduced state). Conclusion: Homeopathic potencies of 2,4-D appear to have a beneficial effect on artificially aged maize seeds: they stimulate growth through better substance conversion from seed rest, and shift the redox capacity towards a reduced environment. Further work is required to determine if this is an useful means of improving maize seed germination and growth.

AB  - The effects of green and far red light on germination of common chickweed (Stellaria media (L.) Vill.) seeds were compared to determine a possible mechanism of activity of green light in the germination process of chickweed. A brief irradiation with far red light on the first day of imbibition was found to inhibit germination at a certain percentage but it was followed by a stimulating effect, which became evident on the second day of imbibition. Green light was not found to inhibit germination and its stimulating effect began simulataneously with the stimulating effect of far red light. The results indicate a possible role of phytochrome A in stimulation by green light.

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.

Do inhibicije parametara fluorescencije Chla i fotosinteze, usled dejstva herbicidom sulfosatom, dolazi tek 6-og dana ogleda, ali je tad gašenje fotosintetskih funkcija listova kukuruza naglo. Međutim, kod kontrolnih biljaka, pomenuti parametri su na kraju ogleda značajno veći kod zasenjenih (Sh) odnosno nezasenjenih (S) biljaka. Pomenuti nalaz isto tumačimo funkcionalno kompenzacionim procesima. 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. To vodi ranoj degradaciji Chla i Chl b, a tek na kraju ogleda i degradaciji karotenoida (što je saglasno nepromenjenim vrednostima NPQ parametra fotoprotekcije lista), kod zasenjenih i sulfosatom tretiranih biljaka kukuruza. Znači, antenske funkcije fotosinteze tokom ogleda nisu bitno ugrožene dejstvom sulfosata. 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. Zasenjivanje tretiranih biljaka kukuruza, raslih u kontrolisanim uslovima, izgleda da vodi drugačijim posledicama, nego kod zasenjenih biljaka raslih u uslovima polja i tretiranih sulfosatom. 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. Znači, dužina i obim zasenjivanja veoma utiču na reakciju biljaka kukuruza na dejstvo sulfosata, što svedoči o značaju 'proizvođač-potrošač' odnosa u tom slučaju.

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.

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. 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. Do inhibicije parametara fluorescencije Chla i fotosinteze, usled dejstva herbicidom sulfosatom, dolazi tek 6-og dana ogleda, ali je tad gašenje fotosintetskih funkcija listova kukuruza naglo. Međutim, kod kontrolnih biljaka, pomenuti parametri su na kraju ogleda značajno veći kod zasenjenih (Sh) odnosno nezasenjenih (S) biljaka. Pomenuti nalaz isto tumačimo funkcionalno kompenzacionim procesima. 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. To vodi ranoj degradaciji Chla i Chl b, a tek na kraju ogleda i degradaciji karotenoida (što je saglasno nepromenjenim vrednostima NPQ parametra fotoprotekcije lista), kod zasenjenih i sulfosatom tretiranih biljaka kukuruza.

AB  - Effects of the herbicide sulphosate on growth, accumulation and distribution of dry weight and photosynthesis in maize plants grown in controlled environment and subjected to sourcesink manipulation at the root were studied. The findings indicate that growth and dry weight accumulation did not significantly correlate with any of the dry mass distribution parameters in those maize plants, but type of the root manipulation influenced parameters of plant growth. Also we found that plants with limited root growth has lower values of ETR parameter of photosynthesis, irrespective of herbicides treatment. As the root is place where cytokinins (plant hormons essential for maintaining photosynthetic structures) are synthesized, we assumed that content of cytokinins in the different manipulated roots influenced growth and photosynthesis of the plants irrespectively of exposition of the plants to the herbicide sulphosate.

AB  - Common ragweed (Ambrosia artemisiifolia L.) is an invasive weed and allergenic species. Its considerable spreading capacity is largely due to the properties of its seeds. We checked the effect of several technical parameters on ragweed germination under laboratory conditions. After stratifying seeds for one, four, seven, ten, thirteen and sixteen weeks, we checked whether and in what way the amount of water in petri dishes, filter paper and cling film used to cover petri dishes affected the percentage and dynamics of seed germination at 22 }2°C. Filter paper, which is normally used in laboratory experiments on seeds, was not found to be necessary. The amount of 2 ml of water was sufficient for seeds stratified for up to seven weeks in 60 mm diametre petri dishes. After longer stratification periods, sporadic drying out was observed in petri dishes containing 2 ml of water, rarely in those with 3 ml of water. After refilling the dishes with small amounts of water, this had no effect on the ultimate germination percentage. Covering petri dishes with cling film was found to be useful but not necessary after long stratification.
