dc.description.abstract | The experiment was carried out at Rimski Šančevi during 2009 in order to investigate the effect of chemical desiccation on 1000-seed weight in three sunflower lines, and to determine the optimal moment for performing desiccation. Desiccation was carried out with herbicide Reglone forte (2 l/ha) repeatedly each 7 days, starting from the end of flowering to harvest maturity. All three lines showed highly significant differences in weight of 1000 seeds, and a highly significant effect of a moment of desiccation on 1000-seed weight. The lowest weight was determined when the treatment was performed 7 days after flowering and the highest when the treatment was performed 28 days after flowering with seed moisture content of 22.23%. The results show that this is the optimal time for chemical desiccation. There was no significant difference in 1000-seed weight between the treatment 28 days after flowering and the following treatments, suggesting that seed filling had been finished. | en |
dc.description.abstract | Ogled je postavljen 2009. na Rimskim Šančevima sa ciljem da se ispita uticaj hemijske desikacije na masu 1000 semena kod tri linije suncokreta, kao i da se utvrdi optimalni momenat za njeno izvođenje. Desikacija je vršena preparatom Reglone forte sa dozom 2 l/ha. Tretiranje je vršeno svakih 7 dana, počev od završetka cvetanja do postizanja žetvene zrelosti. Kod sve tri linije utvrđena je visoko značajna razlika u masi 1000 semena, kao i visoko značajan uticaj momenta desikacije na masu 1000 semena. Najniža masa utvrđena je kod tretmana 7 dana posle cvetanja, a najviša kod tretmana 28 dana posle cvetanja, pri vlažnosti semena od 22,23%. Može se zaključiti da je sa aspekta mase 1000 semena, upravo to optimalno vreme za izvođenje hemijske desikacije. Između tretiranja 28 dana posle cvetanja i kasnijih tretmana nije bilo značajne razlike u masi 1000 semena, što govori da je završeno nakupljanje rezervnih materija u semenu. | sr |
