摘  要:
通过酯酶 (EST)、苹果酸酶 (ME)、磷酸葡萄糖异构酶〔PGI(NADP)〕、磷酸葡萄糖变位酶〔PGM(NAD)〕、超氧化物歧化酶 (SOD) 5种酶系统研究墨兰和春兰 17个变种及品种的同工酶多样性 ,并探讨这些材料间的亲缘关系。 5种酶系统所得的 11个位点中 7个是多态性位点。EST、PGM(NAD)和SOD具有多态性。上述 5种酶系统能够把供试品种和变种区分开 ,并划分为墨兰和春兰类。

摘  要:
Five isozyme systems, EST,ME,PGI(NADP),PGM(NAD) and SOD, were used to study the variation of isozyme in varieties and cultivars of Cymbidium sinense and C. goeringii as well as the relationships among these taxa. Eleven loci were generated. Seven of them were polymorphic. EST, PGM(NAD),SOD were polymorphic, two of them could be used to distinguish all of varieties and cultivars. The result showed that these isozyme systems could be used to distinguish cultivars and varieties clearly, and these cultivars and varieties were divided into C.goeringii and C.sinense
