The trial was conducted at Rimski Šančevi (Serbia) experimental field in 2009 in order to assess the effect of chemical desiccation on oil content in seed of three sunflower inbred lines (L1, L2 and L3). Reglone forte (2 l/ ha) was used for desiccation. Desiccant application was performed at 7-day intervals from the end of flowering to harvest maturity. Seed moisture content was measured prior to each treatment. Seed oil content was determined after harvest. The three lines showed highly significant differences in seed oil content. The highest oil content was found in L3, the lowest in L2. The highest oil content was obtained with the treatment done 21 days after flowering (DAF), when seed moisture was 45.6%. There was no subsequent increase in oil content. Regression analysis showed that the three lines achieved maximum oil content at different seed moisture levels at the time of desiccation (19% to 39%).
