摘　　要：营养贮藏蛋白质在木本植物的生长发育过程中起着重要的作用。应用SDS-聚丙烯酰胺凝胶电泳技术对银杏不同部位的营养贮藏蛋白质进行了研究,经分析初步确定了两种营养贮藏蛋白质组分的分子量,探讨了其季节性变化规律,结果表明银杏皮层中的营养贮藏蛋白质含量均高于木质部中的含量。Vegetative storage proteins （VSPs） played an important role in the growth and development of woody plants. In this paper, the SDS-PAGE technology was applied to study VSPs located in different parts of Ginkgo kDbiloba, and two kinds of VSPs were identified with different molecular weight of 32 KD and 36 KD, and whose seasonal change regulations were discussed, and it was found that the VSP content in cortex was more than that in xylem.
