大豆种子贮存蛋白组成及其相关分析

1988年选用14个,1989年选用15个蛋白质含量差异较大的主要为江淮地区的大豆品种,进行随机区组试验。大豆种子中球蛋白、清蛋白、醇溶谷蛋白以及谷蛋白的品种间平均分别为28.56％、7.50％、1.81％和5.71％,品种间变幅分别为6.08％、10.25％、1.03％和6.51％。清蛋白含量与全蛋白含量。谷蛋白含量与全蛋白含量之间显著正相关,清蛋白含量对种子全蛋白含量品种间差异的相对贡献最大,而球蛋白含量对品种间全蛋白含量差异的相对贡献最小。球蛋白含量与株高、分枝数和单株粒重存在显著的正相关;但株高和清蛋白含量、单株荚数及单株粒数和谷蛋白含量有显著负相关。

STODES ON THE COMPONENTS OF SEED STORAGE PROTEIN AND THEIR CORRELATIONS IN SOYBEAN

The total storage protein of soybean Glycine max (L. ) Merr. ] seed is composed of four components, globulin, albumin, glutelin and prolarnine, and the role of these components in tofu or soybean milk processing is different. Fourteen and fifteen varieties with different protein content were chosen and tested in randomized block experiments in 1988 and 1989 to study the com-ponent contents of storage protein in soybean seeds. The globulin, albumin, prolarnine and glutelin content were 28. 46%, 7. 50%, 1. 81% and 5. 71% of the dry seed weight, respectively, and their range among varieties Were 6. 08%, 10. 25%, 1. 03% and 6. 51%, respectively. The correlations between glutelin, albumin and total protein content showed significant, the albumin content made the greatest contribtion to the varibility of total protein, and in contract, the globulin content the smallest. The globulin were significantly and positively correla-tioned with plant height, No. of branches and single plant yield, while the correlations between plant height and albumin content, glutelin content and No. of pods per plant, No. of seeds per plant were significantly negative.
