摘要
为了选择高产脂、高产材的湿地松优良品系,对从美国引进的10个湿地松高产脂品系的生长与产脂性状进行了综合分析评定,结果表明品系间生长指标及产脂量表现差异显著,其中表现最优的品系是204和215。另外,还从湿地松高产脂试验林中选择出生长与产脂均佳的15株优树,其单株材积比林分平均单株材积大20%以上,单株产脂量比林分平均值大200%左右。
10 high-yeild resin lines of slash pine that originated from USA were introduced from Chinese Academy of Forestry to Jingmen, Hubei province. The properties of these 10 lines of slash pine were comprehensively evaluated. A significant difference of growth and resin index was found among 10 lines, with line 204 and llne 215 the best. 15 plus trees were also selected based on their resin content and growtli, these plus trees might be used as the materials for further selection and breeding of slash pine.
