摘要
对早熟与中熟两组品种,在4个地区两年含油率积累动态进行观察分析。结果表明,灌浆初期的温度是当年油葵含油率高低的重要制约因素;含油率积累速率前期快,后期较慢,且积累高峰期随地域不同而有差异;
The relationship between the dynamics of oil accumulation in seeds of early maturity and medium maturity varities of oil sunflower was studied in 1994~1995 in 4 different regions. The results showed that the temperature in the early filling period was the most important factor to oil content. The higher the temperature was the higher the oil accumulated the accumulative rate of oil content was in early stage after flowering, but lower in late stage after flowering. The accumulative peak period of oil content was different in different regions. There was a significant positive correlation between the accumulation of oil content and the accumulated temperature in the flowering period and diurnal range of temperature.
