dc.description.abstractCommon 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 presented in this paper was done with seeds of two common ragweed populations, which were stored at room temperature after collection. Seed germination and seedling growth (elongation and weight increase) were studied in six different combinations of light, temperature and previous seed exposure to low temperature (4°C). Based on the results obtained, we concluded that germination was better in all treatments that included seed irradiation than in the dark, while seedling growth was more intensive in treatments with seeds exposed for 24h to 4°C temperature before testing.en
dc.description.abstractAmbrozija (Ambrosia artemisiifolia L.) je invazivna korovska vrsta, a predstavlja ozbiljan problem i kao izvor polena koji izaziva alergijske rakcije kod ljudi. Razmnožava se semenom čija klijavost zavisi od većeg broja faktora. Prikupljena semena dve populacije ambrozije su do ispitivanja čuvana na sobnoj temperaturi. Klijavost semena i rast klijanaca, tj. povećanje njihove dužine i mase praćeni su u šest različitih kombinacija svetlosti, temperature i prethodnog izlaganja semena niskoj temperaturi (4°C). Na osnovu dobijenih rezultata utvrđeno je da je u svim tretmanima koji uključuju osvetljavanje semena klijavost bila bolja nego u mraku, dok je rast klijanaca bio najintezivniji u tretmanima sa semenima koja su pre postavljanja ogleda bila izložena temperaturi od 4°C tokom 24h.sr
