| 摘 要： | 对营造在浙江省龙泉市林科所5年生杉木二代种子园家系子代试验林的树高、胸径2个主要生长性状进行了测定和分析。结果表明:树高、胸径2生长性状在家系间达极显著差异水平,且有较高遗传力和中等的变异系数;用树高和胸径2个生长性状,采用独立选择法初选出7个幼林期生长表现较好的家系,树高和胸径分别比试验对照大17.11%和25.73%。

| Abstract: | The two main growth traits(H,D)in 5-year-old Chinese fir family plantation in the second generation seed orchard from Longquan City Forestry Research Institute of Zhejiang Province were determined and analyzed.The results revealed that two main growth traits were highly significant between the families,and have high heritability and middle variation coefficient.7 fast-growing families have been selected by independent selected method with two traits of H and D,H and D increased 17.11% and 25.73% than experi... |
