风媒授粉种子采自福建省14个成熟的柳杉天然林。在实验室和3个林场的苗圃中研究了种子品质和苗木的生长情况,发现我们所研究的大多数性状,在不同林分间或同一林分不同单株间都存在有显著的差异。一年生苗木高生长表现出高度的遗传稳定性,家系×地点互作方差分量非常小(0.38％),是不显著的。估计的家系高生长广义遗传力为0.905。
Wind pollination seeds collected from Fujian Province, 14 mature Cryptomeria natural forest. Seed quality and seedling growth were studied in nurseries of three forest farms in the laboratory and found that most of the traits we studied found significant differences between different or separate stands of the same forest. The annual growth of annual seedlings showed a high degree of genetic stability, and the variance component of family × locus interaction was very small (0.38%), which was not significant. Estimated high growth of the family generalized heritability of 0.905.
