Hemijska desikacija suncokreta – novi izazovi

Abstract

Ispitivan je uticaj hemijskih desikanata na gubitak vlage zrna i semenske kvalitete suncokreta. Herbicidima Kabuki 2.5 EC (a. i. pyraflufen-ethyl, 1 l/ha), i carfentrazoneethyl, (0,4 l/ha) tretirano je 6 CMS roditeljskih linija. Prosečan sadržaj vlage zrna se kod oba tretmana nije značajno razlikovao od kontrolne varijante. Nije bilo vidljivih znakova sušenja drugih biljnih organa u odnosu na kontrolu. Energija klijanja i klijavost semena ispitivani su 40 i 54 dana posle žetve. Nije došlo do pada semenskih kvaliteta u odnosu na kontrolu. Korišćeni herbicidi nisu pokazali zadovoljavajući efekat u desikaciji suncokreta.

The influence of chemical desiccants on grain moisture loss and sunflower seed quality was investigated. 6 CMS parental lines were treated with the herbicides Kabuki 2.5 EC (a. i. pyraflufen-ethyl, 1 l/ha) and carfentrazone-ethyl (0.4 l/ha). The average grain moisture content in both treatments was not significantly different from the control variety. There were no visible signs of drying of other plant organs compared to the control. Germination energy and seed germination were examined 40 and 54 days after harvest. There was no decline in seed quality compared to the control. The used herbicides did not show a satisfactory effect in sunflower chemical desiccation.
