同功酶技术在鹅掌楸属树种分类中的应用研究

Application Study on Classicfication of Liriodenron Tree Species with Isozyme Technique

摘要:

笔者运用同工酶电泳技术和形态学对鹅掌楸属树种的分类进行了探讨,结果表明:各种间不仅在形态上存在很大差异,而且同工酶酶谱也存在很大差异,鹅掌楸在Pgm的基因位点有1条特有的谱带(等位基因d),杂种鹅掌楸2条谱带(等位基因a、d)都不存在;鹅掌楸在Shdh的基因位点有1条特有的谱带(等位基因a),北美鹅掌楸和杂种鹅掌楸都不存在这条谱带.根据这个试验结果可以鉴定鹅掌楸、杂种鹅掌楸、北美鹅掌楸.

Abstract:

The authors have studied classification of Liriodenron using isozyme electrophoresis technique and morphology.The result showed very high variation among varieties of isozyme genetic loci and morphologic type.Liriodenron chinese(Hemsl.) Sarg.has a unique band(allele d) in the Pgm genetic loci,hybrid does not exist on two bands(alleles a,d);Liriodendron chinese(Hemsl.) Sarg.has a unique band(allele a) in the Shdh genetic loci,Liriodendron tulipifera L.and hybrid did not exist on this band.According to the te...
