摘    要:分析了两片杉木子代林伐桩和杉木无性系采穗圃萌条数量的遗传变异情况。结果表明:杉木子代林伐桩萌条数量在产地间、产地内家系间及组合间均存在极显著差异,并有中等以上遗传力;遗传变异系数在37%~39%之间;产地的遗传方差分量与产地内家系间的相近。伐桩萌条数量与基径粗度的关系随伐桩年龄的变化而表现不一;不同砍伐季节伐桩萌条数量也存在较大差异。杉木无性系采穗圃无性系间有效萌条数量存在极显著差异,无性系的萌芽能力有较高的重复力。

关 键 词:杉木  干基萌芽能力  无性系  采穗圃  遗传变异

Abstract:This paper deals with the analyses on genetic variation of coppice shootsquantities in the vegetative propagation nursery and stump of two pieces progeny test planta-lion of Chinese fir.The results showed: there were highly significant differences among theseed source,families of the seed source and compoheritability were of over middle levd.Their geneticsition of coppicx shoots quantity.variation coefficients were betweenT heir37%~39%.The weight of genetic square was similar to that of the seed sourcx and family ofseed source.There were different correlation between coppice shoots quantity of stump andstump diameter with the increase of stump growth. There were differences in different cut-ting season. There were highly significant differences among clones of effectivee coppiceshoots quantity in vegetation propagation nursery for Chinese fir.There was strong repeatingability for the sprouting ability of clones.
Keywords:Chinese fir  sprouting ablilty on the trunk base  vegetative propagation coppice shoots quantity  genetic variation
