Özet
Oil concentration and quality in sunflower (Helianthus annuus L.) are very much affected by environmental conditions such as temperature, precipitation, relative humidity, cloudiness and so on. Sunflower oil quality is determined by its fatty acid composition. Therefore, the objective of this study was to investigate the effect of ecological and topographic conditions on oil content and fatty acid composition in a standard sunflower hybrid. The samples were taken from six zones determined according to their ecological and topographical features. The results showed that oil content and fatty acid composition significantly changed by ecological and topographic conditions. Oil content in seeds varied 39.82-44.30% depending on location. Percentages of major fatty acids such as linoleic, oleic, palmitic and stearic acid were also significantly affected by growth location. As a result, environment or growth condition had a significant effect on sunflower oil content and fatty acid composition. Therefore, growth location is an important factor for meeting market requirements of sunflower oil in terms of quality.
