摘要:
2015 年,对浙江龙泉10 年生杉木Cunninghamia lanceolata 2 代种子园中38 个家系子代的树高、胸径和材积进行测定和分析,同时进行速生型优良家系选择。结果表明,2 代种子园子代的树高、胸径和材积在家系间达极显著差异水平(α= 0.01),且有较高遗传力和中等的变异系数;采用多重对比法根据材积筛选出7 个中期生长表现良好的家系,其树高、胸径和材积分别比对照增加15.15 %,18.83%和59.61 %。
Abstract:
Determinations and analysis were conducted on height, DBH and volume of 38 families of 10-year filial generation from the secondgeneration seed orchard of Cunninghamia lanceolata in 2015 in Longquan, Zhejiang province. The results showed that it had great difference of thethree growth traits among families (α= 0.01), with high heritability and medium variable coefficient. Seven fast-growing families were selected bymultiple comparisons, based on volume growth, their height, DBH and volume was 15.15% , 18.83% and 59.61 % respectively higher than that of thecontrol.
