本文采用相关分析、回归分析等方法对樟子松8个种源亲本的球果、种子及针叶地理变异的研究表明:各种源球果及针叶种源间存在显著的差异。球果宽、种子长,种子宽与纬度呈显著的负相关;种子发芽率同海拔呈极显著的负相关;针叶宽、针叶厚、维管组织区宽与经度呈显著的正相关。依据球果种子及针叶性状将樟子松区划为3个种源区。
In this paper, the correlation analysis, regression analysis and other methods of Pinus sylvestris 8 provenances of cones, seeds and conifers geography variation studies showed that: all kinds of coniferous and coniferous provenances have significant differences. There was a significant negative correlation between the seed germination rate and altitude. The width of cones, the length of seeds, the width of seeds and the width of seeds were significantly negatively correlated with latitude. According to the coniferous seeds and coniferous characters, Scotch Pine was divided into 3 provenance areas.
