The influence of annual changes in temperature and light (PAR) on the induction of Chla fluorescence in situ in Stellaria media (L.) and Plantago maior (L.) / Uticaj godišnjih promena temperature i svetlosti (PAR) na indukciju fluorescencije Chla in situ kod Stellaria media (L.) i Plantago maior (L.)
(Herbološko društvo Srbije, Beograd, 2008)
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 ...
Weed resistance to herbicides in Serbia and worldwide / Rezistentnost korova na herbicide u svetu i kod nas
(Herbološko društvo Srbije, Beograd, 2008)
Since the discovery of the first weed species, Senecio vulgaris L., resistant to triazines, a total of 415 biotypes of weed species have been determined that are resistant to herbicides, i.e. 183 weed species, of which 110 ...
Effects of temperature and light induction of CHL a fluorescence in situ: An ecophysiological view / Uticaj temperature i svetlosti (par) na indukciju fluorescencije CHL a in situ - ekofiziološki pregled
(University of Belgrade, University of Novi Sad, 2008)
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 ...
Mogućnosti suzbijanja korova u soji primenom herbicida / Possibilities of soybean weed control by herbicide application
(Poljoprivredni fakultet - Departman za zaštitu bilja i životne sredine "dr Pavla Vukasovića", Novi Sad, 2008)
Due to the different herbicide efficiency to certain weed species, herbicide choice is predominantly conditioned by weed community composition. The second reason for herbicide choice is their depressive action in soybean ...

(Poljoprivredni fakultet - Departman za zaštitu bilja i životne sredine "dr Pavla Vukasovića", Novi Sad, 2008)
This paper reviews the distribution and frequency of several species from a group of economically harmful, invasive and quarantine weeds (Cannabis sativa, Chenopodium album, Ch. hybridum, Cirsium arvense, Convolvulus ...
Morphophysiological traits and atrazine sensitivity in Chenopodium album L.
(John Wiley & Sons Ltd, Chichester, 2008)
BACKGROUND: A Chenopodium album L. biotype surviving in atrazine-treated Serbian corn fields (VC) was compared against atrazine-susceptible (S) and atrazine-resistant (R) standards. RESULTS: Atrazine (2 kg ha(-1)) killed ...
The effect of environmental conditions during seed maturation on germination of chickweed (Stellaria media (L.) Vill.) / Uticaj uslova sredine tokom sazrevanja na klijanje semena mišjakinje (Stellaria media (L.) Vill.)
