| Abstract: | 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. |
