Studies of biological characteristics of seeds and conditions for their germination have a major importance for planning and executing rational measures of weed control. The aim of this study was to investigate the effect of different temperatures on germination of C. campestris seeds. Three treatments (T1- storage at room temperature; T2 - exposure to 4°C for 30 days; T3 - scarification by concentrated sulphuric acid) differing in manipulation with seeds before germination were tested at different temperatures (5°C, 10°C, 15°C, 20°C, 25°C, 30°C, 35°C, 40°C, 45°C). Germinated seeds were counted daily for ten days and the length of seedlings was measured on the last day. The results showed that differences in germination of C. campestris seeds were very prominent between temperatures, as well as between treatments T1, T2 and T3. Seeds failed to germinate at 5°C and 45°C in all treatments (T1, T2, T3). Germination ranged from 6.25 at 10°C to 96.88%, the highest percentage, achieved at 30...°C.
Izučavanje bioloških karakteristika semena i uslova u kojima klijaju ima veliki značaj za planiranje i realizaciju racionalnih mera za kontrolu korova. Cilj ovog istraživanja je bio da se ispita efekat različitih temperatura na klijanje semena C. campestris. U ogled su bila uključena tri tretmana (T1 - semena čuvana u laboratorijskim uslovima na temperaturi 22- 25°C, T2 - semena koja su prethodno 30 dana izlagana niskoj temperaturi (4°C), T3 - semena koja su skarifikovana koncentrovanom sumpornom kiselinom), pri čemu su svi tretmani ispitivani na sledećim temperaturama: 5°C, 10°C, 15°C, 20°C, 25°C, 30°C, 35°C, 40°C, 45°C. Svakodnevno, u periodu od deset dana, rađeno je prebrojavanje proklijalih semena, a poslednjeg dana su izmerene i dužine klijanaca. Dobijeni rezultati ukazuju da postoje značajne razlike u klijanju semena u odnosu na ispitivane temperature i tretmane. Semena nisu klijala na temperaturama od 5°C i 45°C ni u jednom od rađenih tretmana. Procenat klijanja se kretao od 6,2...5% do 96,88%, pri čemu je najveći procenat u sva tri tretmana zabeležen na temperaturi od 30°C.
