毛竹实生苗选育的初步研究

STUDY ON THE SELECTION OF PHYLLOSTACHYS PUBESCENS SEEDLINGS

于 1 995～ 2 0 0 0年对毛竹实生苗进行了从苗期到幼林的生长对比试验 ,通过对毛竹实生苗逐年的苗高、地径、发笋数三项指标的试验结果表明 :毛竹实生苗个体之间的生长存在着较大的差异 ,反映出毛竹种子的遗传品质存在着差异 ,且遗传品质较差的苗木从苗期到幼林的生长表现都比较差 ,具有相对的稳定性。因此把好实生苗的选择关 ,是提高毛竹实生苗造林成林。

The survey of growth performance of Phyllostachys pubescens seedlings from seedling to young forest had been made from 1995 to 2000. Hight, ground diameter and the number of bamboo shoots are measured and there were distinct difference among the seedlings, which indicated that the hereditary variation lies in the seed. The heredity of seed is relatively stable, for the seedlings of bad hereditary character grow worse from seeding to young forest than those of good. It is concluded that seelings selection is critical in cultivating Phyllostachys pubescens for wood.\;
