Genetic Variation of Srouting Ability on the Trunk Base of Chinese Fir

  • Received Date: 1994-12-16
  • 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.

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.
