摘要
采用ISSR技术分析了泰安徂徕山、青岛胶南、朝阳凌源和葫芦岛绥中4个赤松毛虫地理种群的分子遗传变异。结果表明:葫芦岛地区赤松毛虫遗传多样性相对较高,种群间有了一定程度的遗传分化;相关性分析表明,种群的遗传多样性与海拔呈显著的负相关,与年均温度、年均湿度呈一定的正相关,而与所处纬度相关关系不显著;各种群两两之间的遗传距离与海拔梯度呈正相关趋势。
By means of ISSR,this paper analyzed the molecular genetic variation of four Dendrolimus spectabilis populations collected from Taian（Culai Mountain）,Qingdao（Jiaonan）,Chaoyang（Lingyuan）,and Huludao（Suizhong）.Among the four D.spectabilis populations,the Huludao population had a higher genetic diversity.There existed definite genetic differentiation among the populations.Correlation analysis showed that the D.spectabilis populations genetic diversity was negatively correlated with elevation,positively correlated with mean annual air temperature and humidity,but less correlated with latitude.Besides,the genetic distance between the pairs of the populations was positively correlated with elevation distance.
