以具有相同遗传背景的高、低含油量基因型油菜品系04-1989-9和04-1989-4为材料,研究种子形成过程中含油量与脂肪合成相关酶活性的动态变化及其相关性。结果表明,两品系的种子含油量、6-磷酸葡萄糖脱氢酶（G6PDH）活性、磷脂酸磷酸酯酶（PPase）活性均在开花后逐渐增加,花后24～ 31d达最高峰,且品系间差异均达显著或极显著水平;G6PDH、PPase活性和含油量呈极显著正相关,推测二者是影响含油量的关键因子。

Two lines of rapeseed with high and low oil contents respectively which have the same genetic background were used to study the dynamic changes of oil-content, glucose 6-phosphate dehydrogenase （G6PDH） activity, and phosphafidate phosphatase （PPase） activity during seed formation, and the correlation between enzymes and oil content in Brassica napus was analysed. The results showed that Oil content, G6PDH activity, and PPase activity increased gradually and reached the peak at 24-31 d after flowering. Significant correlation between two lin...
