【摘要】 通过气相色谱对高产脂马尾松无性系后代的松脂组分分析表明:萜烯和树脂酸各组分间呈极显著性差异。萜烯和树脂酸的遗传参数是:无性系重复力为52%—93.2%,遗传增益为25%—92.0%,遗传方差为1.05%—48.61%。同时对无性系后代和半同胞子代的松脂组分进行比较。更多还原

【Abstract】 An analysis of pine resin components was made for the progeny ofPinus massoniana clones with high yield of resin by gas chromatography. Theresults demonstrate that the differences between terpene and each component ofresin acid reach extreme significance level, The genetic parameters of terpeneand resin acid are as follows: the clonal repeatability is 52--93.2%;the geneticgain is 25--92.0%; and the genetic variance is 1.05--48.61%.Meanwhile thecomparisons of pine resin components between the clonal progeny and the half-sib filial generation were also made.更多还原
