不同产地间、产地内杉木过氧化物同工酶的变异研究＊杨自湘李玲关键词杉木、产地、过氧化物同工酶、酶带分离度同工酶是基因活动的产物，用来认识基因的存在表达，由生化表型反映其基因型，将宏观的遗传现象结合到微观的分子水平上加以研究，因而同工酶技术已成功地应用到...

Research on Variation of Peroxidase Isoenzyme in Cunninghamia lanceolata among or within Provenances

Needle samples of 808 two year old Cunninghamia lanceolata seedlings of 18 provenances from 12 provinces were analyzed by peroxidase isoenzyme method.Altogether 11 isoenzyme patterns were observed,in which 86.1% of the samples showed isoenzyme pattern I,while the geographical latitudes where these provenances located showed significantly negative correlation with frequencies of isoenzyme pattern I.More than half of these 18 provenances showed little genetic variation and only 45% of the provenances showed obvious variation.Polymorphism and bigger divergence D 2 were found in 4 provenances,Yuqing, Liuba,Jinzai and Liannan,which seemed to be correlated with the original production locations of the provenances.
