近年来,人们发现同功酶的变异,可直接地等于等位基因变异。这样就有可能用分析同功酶变异来研究林木群体遗传变异和遗传多型性。红松(Pinus koraiensis)是我国东北的天然林生态系统主要树种之一,为了分析红松天然林群体的遗传变异,我们使用电泳技术测定了休眠种子大配子体组织酯酶同功酶的变异。为分析红松天然林群体确定酯酶型;借助酯酶同功酶等位基因分析、研究红松群体遗传组成;研究酯酶同功酶最普遍等位基因频率在我国东北山区群体间的分布。一、材料和方法
In recent years, people found that isozyme variation, can be directly equal to allelic variation. In this way, it is possible to study the genetic variation and genetic polymorphism of tree populations by analyzing isozyme variation. Pinus koraiensis is one of the major tree species in the natural forest ecosystem in Northeast China. To analyze the genetic variation of natural populations of Pinus koraiensis, we used electrophoresis to determine the variation of esterase isoenzymes in the dormant giant gametophyte tissue. To determine the esterase type for the population of natural Korean pine forest. To study the genetic composition of the Korean pine population by allelic analysis of esterase isozymes. To study the distribution of the most common alleles of esterase isozymes in the mountainous areas of Northeast China . First, materials and methods
