AB  - Temperature and light may be considered the most important factors affecting seed germination in the presence of several other factors crucial for germination (e.g. water, oxygen, plant hormones). The present study aimed to determine temperature values and corresponding modes of light that are suitable for germination of Artemisia vulgaris L., Amaranthus retroflexus, Ambrosia artemisiifolia L., Cephalaria transsilvanica (L.) Schrader and Stellaria media (L.) Vill. under controlled conditions. Before the experiment began, the collected and dried seeds were stored in the dark, at room temperature. The seeds germinated in distilled water in glass Petri dishes. Amaranthus retroflexus, Ambrosia artemisiifolia and Artemisia vulgaris seeds were stratified before germination. The temperatures at which seed germination occurred differed for each species. The seeds germinated under light and/or in the dark. The results showed that light either failed to affect or stimulated germination. There was no statistically significant difference in the germination of Amaranthus retroflexus and Artemisia vulgaris seeds over the whole temperature range investigated, while seeds of the other investigated species had a narrower range of temperatures suitable for germination.
AB  - Uz prisustvo neophodnih faktora klijanja (voda, kiseonik, biljni hormoni), temperatura i svetlost se mogu smatrati najvažnijim činiocima koji utiču na klijanje semena. Cilj naših istraživanja je bio da se odrede vrednosti temperature i odgovarajući režimi svetlosti pogodni za klijanje semena Artemisia vulgaris L., Amaranthus retroflexus L., Ambrosia artemisiifolia L., Cephalaria transsilvanica (L.) Schrader i Stellaria media (L.) Vill. u kontrolisanim uslovima. Prikupljena semena su nakon sušenja čuvana do početka eksperimenta u mraku, na sobnoj temperaturi. Semena su isklijavana u staklenim Petri kutijama, u destilovanoj vodi. Semena Amaranthus retroflexus, Ambrosia artemisiifolia i Artemisia vulgaris su prethodno stratifikovana. Temperature na kojima je vršeno isklijavanje semena su se razlikovale za različite vrste. Semena su isklijavana na svetlosi i/ili u mraku. Dobijeni rezultati eksperimenta pokazuju da svetlost ili nije imala uticaja, ili su semena bolje klijala na svetlosti. Semena Amaranthus retroflexus i Artemisia vulgaris su klijala bez statistički značajne razlike u čitavom dijapazonu ispitivanih temperatura, dok su semena preostalih ispitivanih vrsta imala uži opseg povoljnih temperatura za klijanje.

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  - Upoređivan je uticaj zelene i tamnocrvene svetlosti na klijanje semena mišjakinje (Stellaria media (L.) Vill.) da bi se utvrdio mogući mehanizam delovanja zelene svetlosti na ovaj proces kod mišjakinje. Pokazano je da kratkotrajno osvetljavanje tamnocrvenom svetlošću tokom prvog dana imbibicije inhibira klijanje u određenom procentu, a zatim počinje da deluje stimulativno, što je potpuno očigledno tokom drugog dana imbibicije. Zelena svetlost ne inhibira klijanje, a njen stimuliativni efekat počinje u isto vreme kada i stimulatvni efekat tamnocrvene svetlosti. Rezultati ukazuju na moguću ulogu fitohroma A u stimulativnom delovanju zelene svetlosti.

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.
AB  - Ambrozija (Ambrosia artemisiifolia L.) je invazivna korovska i alergena biljna vrsta. Svoju veliku zastupljenost u značajnoj meri duguje osobinama svog semena. U našem radu je proveravan uticaj nekih tehničkih parametara na klijanje ambrozije u laboratorijskim uslovima. Nakon što su semena stratifikovana jednu, četiri, sedam, deset, trinaest i šesnaest nedelja ispitivano je da li i na koji način količina vode u Petri kutijama, upotreba filter papira i korišćenje prijanjajuće folije za uvijanje Petri kutija utiču na procenat i dinamiku klijanja semena na 22 }2°C. Pokazalo se da filter papir, koji se inače redovno koristi u laboratorijskim eksperimentima sa semenima, nije neophodno koristiti. Za semena stratifikovana do sedam nedelja količina vode od 2 ml je, za korišćene Petri kutije prečnika 60 mm, bila dovoljna. Pri dužoj stratifikaciji je sporadično dolazilo do isušivanja Petri kutija sa 2 ml, ređe sa 3 ml vode. Uz blagovremeno dolivanje vode, to nije uticalo na krajnje procente klijanja. Uvijanje Petri kutija prijanjajućom folijom se pokazalo korisnim, mada ne i neophodnim, pri dužoj stratifikaciji.

AB  - Effects of the herbicide sulphosate on growth, accumulation and distribution of dry weight and photosynthesis were investigated in maize plants grown in field conditions and previosly subjected to influence of kinetine, because of potentially protective role of this phytohormone. This phytohormone not protected maize plants from phytotoxic action of herbicide sulphosate, because of inhibition of growth, accumulation and distribution of dry weight and also photosynthesis, irrespective of kind of pretreatment of plants (with or without kinetine). Also we concluded that Fv/Fm and RFd parameters of Chla fluorescence is good nondestructive indicators of plant physiological status, both in control and sulphosate-treated maize plants.

AB  - Chla fluorescence, as a mode of estimation of photosynthesis, is especially sensitive to changes in temperature and light intensity (PAR). This enables us to study the influence of those ecophysiological parameters on photosynthesis in native plants. In this article, we examined the effect of annual changes in temperature and PAR on the parameters of Chla fluorescence in Stellaria media (L.), a plant species more frequent in colder periods of the year, and Plantago maior (L.), which is more frequent in warmer periods. Lower PAR and temperature slowed down the electron transport in PS2, but lower temperatures reduced the quantum efficacy of PS2 and improved processes in the antennae system and the size of plastoquinone pool of PS2 in Stellaria media (L.). Lower temperatures reduced quantum efficacy and slowed down the electron transport in PS2 in Plantago maior (L.). The facts that PAR (as well as temperature) affects photosynthesis, and that lower temperatures activate processes in the antennae system and those on the acceptor side of PS2 as a 'counterbalance' to the inhibition of quantum efficacy and electron transport in PS2, caused by low temperatures, point at possible explanations of low-temperature resistance of photosynthesis in Stellaria media (L.). On the other hand, low temperatures caused inhibition of quantum efficacy and electron transport in the PS2 of Plantago maior (L.), which caused low-temperature photoinhibition and stepped quenching of all physiological processes in the species. This might be the reason for the different levels of acclimation to low temperatures and different life strategies of the two species living in close vicinity.
AB  - Fluorescencija Chla, kao pokazatelj fotosinteze, posebno je osetljiva na promene temperature i intenziteta svetlosti (PAR). To omogućava praćenje uticaja ovih ekofizioloških parametara na fotosintezu nativnih biljaka. U ovom radu dat je pregled uticaja godišnjih promena temperature i PAR na parametre fluorescencije Chla kod Stellaria media (L.), biljne vrste zastupljenije u hladnijem delu godine i Plantago maior (L.), biljne vrste zastupljenije u toplijem delu godine. Manje vrednosti PAR i temperature usporavaju transport elektrona u PS2, sniženje temperature umanjuje kvantnu efikasnost u PS2 i pozitivno deluje na antenske procese i veličinu pula plastohinona u PS2 kod Stellaria media (L.). Sniženje temperature umanjuje kvantni prinos i usporava transport elektrona u PS2 kod Plantago maior (L.). Činjenica da i PAR (pored temperature) deluje na fotosintezu, kao i da sniženje temperature aktivira antenske i procese na akceptorskoj strani PS2, kao "protivtežu" inhibiciji kvantne efikasnosti i transporta elektrona u PS2, uzrokovanoj niskim temperaturama, ukazuje na moguće uzroke niskotemperaturne otpornosti fotosinteze kod Stellaria media (L.). Nasuprot tome, kod Plantago maior (L.) niska temperatura uzrokuje inhibiciju kvantne efikasnosti i transporta elektrona u PS2, što dovodi do niskotemperaturne fotoinhibicije i postepenog gašenja svih fizioloških procesa kod te vrste. To bi moglo biti objašnjenje različite prilagođenosti na niske temperature i različitih životnih strategija ovih vrsta, koje žive u bliskom susedstvu.

The facts that PAR (as well as temperature) affects photosynthesis, and that lower temperatures activate processes in the antennae system and those on the acceptor side of PS2 as a 'counterbalance' to the inhibition of quantum efficacy and electron transport in PS2, caused by low temperatures, point at possible explanations of low-temperature resistance of photosynthesis in Stellaria media (L.). On the other hand, low temperatures caused inhibition of quantum efficacy and electron transport in the PS2 of Plantago maior (L.), which caused low-temperature photoinhibition and stepped quenching of all physiological processes in the species. This might be the reason for the different levels of acclimation to low temperatures and different life strategies of the two species living in close vicinity., Fluorescencija Chla, kao pokazatelj fotosinteze, posebno je osetljiva na promene temperature i intenziteta svetlosti (PAR). To omogućava praćenje uticaja ovih ekofizioloških parametara na fotosintezu nativnih biljaka. U ovom radu dat je pregled uticaja godišnjih promena temperature i PAR na parametre fluorescencije Chla kod Stellaria media (L.), biljne vrste zastupljenije u hladnijem delu godine i Plantago maior (L.), biljne vrste zastupljenije u toplijem delu godine. Manje vrednosti PAR i temperature usporavaju transport elektrona u PS2, sniženje temperature umanjuje kvantnu efikasnost u PS2 i pozitivno deluje na antenske procese i veličinu pula plastohinona u PS2 kod Stellaria media (L.). Sniženje temperature umanjuje kvantni prinos i usporava transport elektrona u PS2 kod Plantago maior (L.). Činjenica da i PAR (pored temperature) deluje na fotosintezu, kao i da sniženje temperature aktivira antenske i procese na akceptorskoj strani PS2, kao "protivtežu" inhibiciji kvantne efikasnosti i transporta elektrona u PS2, uzrokovanoj niskim temperaturama, ukazuje na moguće uzroke niskotemperaturne otpornosti fotosinteze kod Stellaria media (L.). Nasuprot tome, kod Plantago maior (L.) niska temperatura uzrokuje inhibiciju kvantne efikasnosti i transporta elektrona u PS2, što dovodi do niskotemperaturne fotoinhibicije i postepenog gašenja svih fizioloških procesa kod te vrste. To bi moglo biti objašnjenje različite prilagođenosti na niske temperature i različitih životnih strategija ovih vrsta, koje žive u bliskom susedstvu.",

AB  - The timing and dynamic of seed germination of weed plants and factors affecting them make an important segment of knowledge required for planning weed control in agricultural fields. Environmental conditions existing during seed maturation are the most immediate factor affecting morphological and physiological properties of seeds. We investigated the effect of environmental conditions existing during seed maturation of chickweed (Stellaria media (L.) Vill.), a frequent and widespread weed species, on their germination in the dark and after irradiation. Seeds were sampled from chickweed plants grown inside a glasshouse and those growing wild outdoors in the vicinity of the glasshouse at 3-9 day intervals from mid-February to early June 2007. When fruits were setting in both populations simultaneously, the seeds were collected on the same dates inside and outside the glasshouse. Chickweed plants that grew outdoors began flowering and fruiting more than a month later than those growing in the glasshouse. Plants growing inside the glasshouse stopped fruiting about 20 days after those around the glasshouse. Two months after the last harvest, in August, germinability of the collected seeds was investigated. Despite the different conditions in which seeds had matured, no statistically significant difference was detected in germinability in the dark between the seeds sampled inside and outside the glasshouse, except in two of the 14 pairs of samples collected on the same dates. On the other hand, there were considerable and statistically significant differences in germinability depending on sampling dates. The lowest germination was found in samples collected both inside and outside the glasshouse in late March and early April. Irradiation of imbibing seeds with white daylight stimulated germination of all samples and significantly decreased the differences in germinability of seeds collected on different dates, while not eliminating them fully.

Uslovi sredine prisutni tokom sazrevanja semena su prvi faktori koji utiču na kasnije morfološke i fiziološke osobine semena. U ovom radu je ispitivan uticaj uslova sredine tokom sazrevanja semena mišjakinje (Stellaria media (L.)

U vreme kada su obe populacije plodonosile, semena su brana istog dana i ispred staklare i u staklari. Biljke mišjakinje koje su rasle oko staklare počele su sa sporadičnim cvetanjem oko 15 dana kasnije od biljaka u staklari, ali su, zbog dužeg perioda hladnog vremena koji je usledio, sa masovnijim cvetanjem i plodonošenjem počele više od mesec dana kasnije od biljaka iz staklare. Biljke u staklari su prestale da plodonose dvadesetak dana posle biljaka oko staklare. Dva meseca nakon poslednjeg branja, tokom avgusta, ispitivana je klijavost ubranih semena. I pored različitih uslova u kojima su semena sazrevala nije bilo statistički značajne razlike u klijanju u mraku semena ubranih u staklari i ubranih oko staklare, osim u dva od četrnaest parova uzoraka ubranih istog dana.

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  - 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.

abstract = "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., 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.",

AB  - Effects of the herbicide sulphosate on growth, accumulation and partitioning of dry weight and photosynthesis in maize plants subjected to source-sink manipulation at the root were studied. The findings indicate that growth and dry weight accumulation correlate significantly only with the dry mass ratio and/or volume of the root (RMR, Vr, respectively), while a significant negative correlation was found with stem mass ratio (SMR) and generally with leaf mass ratio (LMR), which reflects an irregular distribution of carbohydrate metabolism in maize plants. As the root is where cytokinins, the plant hormons essential for maintaining photosynthetic structures, are synthesized, we assumed that the root status under stress caused by the herbicide sulphosate could be one of the factors of stability/sensitivity of photosynthesis/photosynthetic structures in plants exposed to this herbicide.
AB  - U radu je razmatran uticaj herbicida sulfosata na rastenje, akumulaciju i preraspodelu suve mase, kao i fotosintezu biljaka kukuruza na kojima je vršena manipulacija "proizvod-potrošač" odnosa na nivou korena. Nađeno je da akumulacija suve mase značajno Koreliše samo sa zapreminom i/ili udeonom suvom masom korena (Vr, RMR), a negativno značajno sa udeonom suvom masom stabla (SMR) i (uglavnom) listova (LMR), što je u skladu sa neravnomernom preraspodelom ugljenohidratnog metabolizma kod biljaka kukuruza. Poznato je da je koren mesto sinteze citokinina, biljnih hormona neophodnih u održavanju fotosintetskih struktura. Pošto rezultati ukazuju na značaj statusa korena u uslovima stresa izazvanim herbicidom sulfosatom, smatramo da isti može biti jedan od faktora stabilnosti /osetljivosti fotosinteze/ fotosintetskih struktura kod biljaka izloženih dejstvu pomenutog herbicida.

AB  - Dodder (Cuscuta spp.) is the most wide-spread parasitic plant in our regions. Over the past several years it has increasingly expanded. Apart from growing in alfalfa and red clover as its main host crops, it is now beginning to pose a growing threat to the other crops, as well. About ten dodder species had been determined in Serbia in the past, but they have been out of focus of detailed research in the past three decades. Two dodder species have been identified as important: the small-seeded (Cuscuta trifoli Bab.), and large-seeded (C. campestris Yuncker). They differ in many respects, including the loci of binding to their host-plants. Methods of controlling dodder include preventive measures, and mechanical and chemical control.

Poslednjih godina primećena je njena ekspanzija, a pored lucerke i deteline, kao njenih osnovnih domaćina, počinje da ugrožava i druge gajene biljke. Zakonska regulativa, kojom se sprečava širenje viline kosice semenom, nedovoljno se poštuje. U zaštiti useva se ne poklanja dovoljno pažnje borbi protiv viline kosice, ruderalna staništa oko naših njiva su izrazito zakorovljena i pravi su rasadnik ovog parazita, te ovakvo stanje izaziva sve veće probleme. Najefikasniji način borbe sa vilinom kosicom je sprečavanje njenog unošenja u useve, ali kada se ona javi, primena herbicida može dati zadovoljavajuće rezultate.
