摘要
研究结果表明,华山松种源生长量地理变异呈纬向渐变型;在亚群体内林分效应>家系效应>家系内个体效应;年生长周期呈"S"型曲线;遗传型X环境互作极显著;种源间树高生长量的稳定性程度不同;性状遗传相关密切。
The results of this study show that the geographic variation of provenance growth of Pinus armandii tends to be the latitudinal decline.In a sub-popu- lation,the stand genetic effect is larger than the family effect which is larger than the individual effect.The annual growth cycle appears to be an s-shaped one.The effect of tree height growth among the provenances is different,and the correlation of character inheritance is close.
