Some environmental effects on the oil yield components of sunflower seeds

Agronomic approaches in yield and quality stability of high oleic sunflowers (Helianthus annuus L.)

“…This result is not necessarily a contradiction but rather a positive reflection of the sunflower's oil productivity to the better water availability at the flowering stage at the southern location Eckartsweier in the study years 2003 and 2005. It was also found by Pinthus (1963) that the high temperatures together with the high evaporation during the flowering cause decreases in oil yield components. Despite of the higher temperatures, the precipitation was also higher at Eckartsweier which probably led to the higher oil contents.…”
