Changes in oil content and its fatty acid composition in two sunflower cultivars (with high and normal oleic acid contents) as affected by different temperatures during seed maturation.
Abstract
Sunflowers cv. Lipo (high oleic acid content) and Albena (normal content) were exposed during seed maturation to day/night temperatures of 27/22C or 16/10C. Seed lipid content stabilized 45 days after anthesis. Oleic acid content was higher at the higher temperature in both species, as a result of lower desaturase activity. 9 ref. Sunflowers cv. Lipo (high oleic acid content) and Albena (normal content) were exposed during seed maturation to day/night temperatures of 27/22C or 16/10C. Seed lipid content stabilized 45 days after anthesis. Oleic acid content was higher at the higher temperature in both species, as a result of lower desaturase activity.
