摘要
本文对51个侧柏种源1年生苗木根系性状的观测数据进行了分析。结果表明,种源间在根系性状中存在着显著的遗传分化,并有明显的地理变异趋势。据此,划分出3个地理类群和5个根系类型。
The root data of one year old seedings from 51 provenances of Platycludus orientalis were analysed.The results indicated that significant genetic differences existed in root characteristics from the different provenances and that the tendency of geographic variations were significant.Therefore,the provenances were classified into three geographic groups and five form types
