Variation in Characteristics and Their Selection Potentials of Plus Trees Among Natural Stands of Picea asperata

    摘要
  • 摘要: 利用7个天然林林分中初选优树的22个性状资料,分析了性状在林分间的变异情况,并定性地指出各目的性状在林分、个体间的选择效果.运用综合坐标评定法,确定了参选林分的选择潜力,并对75株初选优树给予分类评价.

     

    Abstract: Twenty-two characteristics of plus trees that had been phenotypically selected in 7 natural stands of Pieca asperata.were analysed on their variation among the stands.Selection effectiveness of the characteristics was qualitatively pointed out on levels of the stands and the trees.A comprehensive evaluation of coordinates was applied to defne potentials for selection in the stands and to evaluate the 75 selected plus trees in 3 types.
