摘要:
从浙江建德刨花楠天然林中选择出优树22株,采集优树种子育苗,在建德市建德林场进行造林试验,结果表明造林后6年生刨花楠优树子代林树高和胸径2个生长性状在家系间存在极显著差异,且2个生长性状有较高的广义遗传力和中等的变异系数;根据树高和胸径,采用独立选择法,初选出5个幼林期生长较快的家系,6年生时其树高和胸径的平均值分别为4.51 m和4.83 cm,比母树林混种的树高和胸径分别高出14.18%和16.67%。
Abstract:
The seeds of 22 dominant trees selected in natural Machilus pauhoi forest were collected in Jiande City, Zhejiang Province. The afforestation trials were conducted by using the container seedlings. The results showed that the tree height and DBH of 6-year-old stand were high in both broad heritability and medium in variation coefficient and differed significantly among different families. And five quick-growing families have been selected in young stand stage. The average of tree height and DBH of five selected families are 4.51 m and 4.83 cm, increased by 14.18% and 16.67%, compared with those of the stand from mixed seeds respectively.
