摘要
向日葵早熟与中熟两组品种在4个地区两年含油量积累动态的观察结果表明，灌浆初期的温度是当年油葵含油量高低的重要制约因素；含油量积累速度和积累高峰期随地域不同而有差异；含油量的积累与花期积温和气温日较差呈显著正相关。
Accumulative dynamics of seed oil content of early maturity and medium maturity varieties was analyzed in 4 different regions during two years. The results showed that temperature during the early filling period was the most important factor to oil content. Accumulative rate and accumulative peak of oil content was different as regions. There were significant positive correlations between the accumulation of oil content and the accumulative temperature (>10℃)in flowering period and temperature difference between day and night respectively.
