Abstract
The experiment was conducted to determine the effects of the ratio of leaf
removal from bottom of plants (0, 4, 8 and 12 leaves / plant) shortly before flowering on
yield components and some quality characters of sunflower ecotypes (Amasya, Uak,
Kırehir, Erzurum, Idır-2, Çorum-2, Edirne -1, Çorum-1, Line-1 ve Idır-1).
Based on the results, seed setting, seed yield, kernel ratio, crude oil and crude
protein content of seeds crude oil yield and crude protein yield changed with different
degrees of leaf removal. Head diameter, seed setting, seed yield, 1000 seed weight,
kernel ratio, crude oil, crude protein content, crude oil yield and crude protein yield
varied with degree of leaf defoliation of some ecotypes while those characters were not
affected by defoliation in some ecotypes.
