摘　　要：大豆在开花、结荚及鼓粒期干旱，蛋白质含量均上升，脂肪含量及脂肪蛋白总量则下降，以鼓粒期干旱的变化为最显著；荚期干旱的不饱和脂肪酸（主要是油酸１８：１）含量的提高与饱和脂肪酸（主要是棕榈酸１６：０）含量的降低均极显著，亚麻酸含量亦下降。The experiment showed that under dry treatment from flowering, podding to seed-filling stages,the contents of protein increased, the contents of oil and the total contents of oil and Protein decreased. The change in seed-filling stages is obvious; Under dry treatment at podding,the contents of unsaturated acids(oleic acid) increased,the contents of saturated acids (palmitic acid) decreased, both of them are very clear.The contents of lindenic acid are the lowed.
