【摘要】 以亚麻品种82(50)为材料,研究了亚麻籽粒中主要脂肪酸、蛋白质和糖积累的规律,结果表明:在亚麻籽粒发育成熟的过程中,棕榈酸、亚油酸含量持续下降,当籽粒完全成熟时降至最低;油酸和亚麻酸含量持续增加,当籽粒完全成熟时含量最高;硬脂酸在籽粒发育10～25d,其含量逐渐提高,以后逐渐下降。蛋白质随着籽粒发育成熟其含量持续提高,且蛋白质含量的提高主要发生在籽粒发育成熟的30d以前。总糖随籽粒发育成熟含量迅速下降,当种子完全成熟时降至最低。更多还原

【Abstract】 Analysis for accumulating rule of primary fatty acids,proteins and sugar in the seeds of 82(50) Linum usitatissimum cv.were conducted.The results indicated that,in the process of maturing of seeds,palmitate and linoleate contents declined continually until the seeds matured fully,they reached the lowest degree.At the same time,oleate and linolenic acta contents increased continually,and finally reached the highest degree.In the first 10 to 25 days of growth of seeds,stearic acid content increased continually and then has a downward trend.Protein content increased continually in the whole process of maturing of seeds,and the increase of it occurred mainly in the last 30 days.Total sugar contents decreased rapidly and reached the lowest degree when the seeds matured fully.更多还原
