中文摘要：

依据银杏枝条中32和36ku蛋白质含量的明显季节变化,推测它们是银杏的营养贮藏蛋白质。采用间接免疫组织细胞化学定位技术,对这2种蛋白质进行细胞化学定位。32和36ku蛋白质具有一定的免疫相关性,它们分布在一些皮层薄壁细胞和韧皮部的韧皮薄壁细胞中,存在于这些细胞的小液泡里。研究结果揭示这2种蛋白质的组织分布式样,为这2种蛋白质是银杏的营养贮藏蛋白质提供有力证据。

英文摘要：

Both 32 ku and 36 ku proteins had been in speculated as the vegetative storage proteins the branches of Ginkgo biloba based on the obvious seasonal changes in their contents.The cytochemical localization of the two proteins was studied with the indirect immuohistochemistry localization technigue.The proteins with a certain immune correlation,were distributed in the vacuole of the parenchyma cells of cortex and the parenchyma cells of phloem.The results revealed tissue distribution pattern of the two kinds of protein,and in the meantime the results provided strong evidence to support the two kinds of protein as the vegetative storage proteins of G.biloba.
