高油大豆品种蛋白质和脂肪积累规律初探

Primary study on protein and lipid accumulation in high oil content soybean varieties

以3个高油大豆品种(绥农14、红丰9、东农47)为试验材料,在2003—2004不同年份探讨高油大豆品种蛋白质和脂肪积累的变化规律。结果表明:高油大豆品种在不同年份间,脂肪含量的相对排序保持不变。油分含量高的品种,蛋白质含量年份间变异较小;油分含量低的品种,则变异较大。高油大豆的蛋白质含量积累呈现出“高—低—高”趋势,并且种子成熟后的蛋白质含量要小于初期测量时的含量;高油大豆脂肪含量积累呈现了“低—高—低”趋势,并且种子成熟后的脂肪含量要高于初期测量时的含量。

Three high oil content soybean varieties were used to study the change of protein and fatty accumulation in high oil content soybean variety in 2003--2004. The results indicated the relative order of fatty content of the varieties kept unchanged in different year. Protein accumulation showed a tendency of high - low - high as the seeds develop towards maturity, and the protein content was lower maturity than that at earlier stage. On the other hand, the fatty accumulation presented low - high - low tendency and the fatty content was higher after maturity than that at earlier stage.
