摘要
根据全国12个省(区、市)24个试验点1983、1984年两次侧柏全分布区种源试验的数据,对1—3年生苗木生长和越冬性状进行了分析。结果表明:种源间在苗高、地径、越冬受害程度上存在显著的差异。地理变异模式是以纬向变异为主的渐变类型,并具有明显的气候生态特征。
Based on the data of wide range provenance trial of Platydadus orientalis carried out in 1983 and 1984 at 24 experimental points,the growth and overwintering characteristics of the seedlings at the age of 1-3 years were analysed. The results showed that significant differences existed in height, diameter at butt end and frost damage of seedlings originated from different provenances. Latitudinal cline was the character of geographic variations with apparently climatic ecological traits.
