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 ...
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 ...
Susceptibility of the species Conyza canadensis (L) cronquist and Conyza bonariensis (L) cronquist to glyphosate / Osetljivost vrsta Conyza canadensis (L) cronquist i Conyza bonariensis (L) cronquist na glifosat
(Herbološko društvo Srbije, Beograd, 2008)
Changes in leaf anatomy were examined in suspectedly resistant populations of C. canadensis and C. bonariensis after application of 2, 4 and 8 L ha-1 of the product Touch down (500 g a.i. glyphosate L-1). Samples for the ...
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 ...
Study of the pale potato cyst nematode biological characteristics (Globodera pallida Stone) / Ispitivanje bioloških karakteristika blede krompirove cistolike nematode (Globodera pallida Stone)
(Poljoprivredni fakultet - Departman za zaštitu bilja i životne sredine "dr Pavla Vukasovića", Novi Sad, 2008)
Biological characteristics of Globodera pallida, originating from Kladnica locality, have been studied. The biological cycle of G. pallida begins with egg stage. Eggs are inside the cyst, protected from outside influence ...
Germination of common ragweed seeds under different light and temperature conditions / Klijavost semena ambrozije pri različitim uslovima svetlosti i temperature
(Herbološko društvo Srbije, Beograd, 2008)
Common ragweed (Ambrosia artemisiifolia L.) is an invasive weed and a troublesome species whose pollen causes allergies in humans. It multiplies by seeds and their germination depends on a number of factors. The investigation ...
Germination of Iva xanthifolia, Amaranthus retroflexus and Sorghum halepense under media with microorganisms
(Journal of Plant Diseases and Protection, Supplement, 2008)
This investigation focused on testing the germination of three weed species (Iva xanthifolia Nutt., Amaranthus retroflexus L. and Sorghum halepense (L.) Pers.) under the influence of several microorganisms: a population ...
On the identity of Rhinusa hispida (Brulle) and its current synonyms (Coleoptera : Curculionidae)
(Magnolia Press, Auckland, 2008)
From examination of type specimens the authors establish that Rhinusa hispida sensu auctorum is not the same species as R. hispida (Brulle, 1832), which is instead synonymous with R. tetra (Fabricius, 1792) (syn. n.). ...
Distribution of some harmful, invasive and quarantine weeds on the territory of Serbia, Part II: Spatial distribution and frequency of nine weeds species / Distribucija nekih ekonomski štetnih, invazivnih i karantinskih korovskih vrsta na području Srbije, II deo - prostorna distribucija i zastupljenost devet korovskih vrsta
(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 ...
