摘 要 ：本文利用主分量分析和判别分析技术,研究了油松遗传变异问题。结果表明,油松的地理变异具有生态型变异的特点,并划分了7个生态型:1.西北型:抗寒性强,生长慢,针叶短;2.东北型:生长中等,抗寒性强;3.西南型:生长较快,抗寒性较差;4.中西型:生长快,抗寒性较差;5.中部型:生长中等,抗寒性较强;6.东部型:生长快,抗寒性较差;7.南部型:生长较快,抗寒性差,再生长现象最强烈,针叶长而细。油松生态型的研究可为种子区划工作提供直接的依据。

Abstract:With the methods of principal component analysis and discriminant analysis, the genetic variations in Pinus tabularformis Carr. were studied. The result showed that the geographical variations in the species were in the character of ecotypical variations and seven ecotypes were divided. Our research can be directly used as a basis for seed zone classification in Pinus tabulaeformis Carr.。
