摘要
以巴山松大配子体为酶源材料，应用同工酶电泳技术，分析了巴山松３个地理群体的谷氨酸草酰乙酸转氨酶（ＧＯＴ）同工酶。结果表明：巴山松天然群体ＧＯＴ同工酶由３个多态基因位点组成，分别定名为ＧＯＴ－Ａ，ＧＯＴ－Ｂ和ＧＯＴ－Ｃ；３个地理群体不论在酶谱表型，还是各位点等位基因频率分布上，都表现出较高的变异水平。
Seed samples were collected from 3 natural geographical populations of Pinus henryi Mast. and megagametophytes were analyzed through the methord of horizontal polycrylamide gel electrophoresis at 3 loci of GOT.The results showed that the GOT isozyme of Pinus henryi Mast. consisted of three polymorphic loci: GOT-A,GOT-B and GOT-C.The 3 populations at various regions showed high variation not only on the patterns of enzyme but also on the distribution of gene freguency at various loci.
