摘要
对应用套式设计的3个亚区、9个产地的108株红松优树子代10年生树高测定表明,亚区间和家系/产地/亚区间差异显著、极显著,家系间的变异量相当于群体间的变异量。多重比较结果,超过对照的78个家系,占参试总数722%;达显著水准超过对照53%以上的有3个家系,占参试总数27%。
Reasons of genetic variations of Pinus koraiensis were analyzed through experiments in this paper.Height of tenyearold young trees from 108 trees in three subregions and nine provenances were measured. Analysis indicates that remarkable difference exists between various subregions,families,and provenances. Compared with control,78 families have higher growth and three of them have a remarkable increment of 53%.\=
