3个熟期类型大豆品种发育籽粒脂肪酸组分变化

超早，极早和中晚3个熟期类型大豆品种籽粒发育进程中，亚油酸含量持续上升，棕榈酸和硬脂酸含量缓慢下降，油酸含量先增后降；3个早熟品种的亚麻酸含量缓慢降低而中熟品种则几乎没有变化，亚油酸与籽粒发育天数呈显著正相关，棕榈酸和油酸呈显著负相关，其它脂肪酸之间及其与籽粒发育天数之间的相关关系因品种熟期类型而异。

Analysis on Fatty Acid Composition in Developing Seed of Three Maturity Soybean

The content of linoleic acid was increased in series,and that of palmitic acid and stearic acid were decreased slowly.The content of oleic acid was increased early and decreased later during the course of three maturity developing soybean seeds.The lino lenic acid content of two early maturity varieties were decreased slowly while that of late-middle maturity variety varied slightly;Linoleic acid was significant positive correlated with the day of developing seed.Palmitic acid had significant negative correlation with the oleic acid.The correlation in other fatty acid or between other fatty acid and the developing day varied with the variety''s maturity type.
