| 摘 要： | 对１９个杉木初选半同胞优良家系进行育苗。结果表明：优良家系种子的发芽势、功木的抗病性及高生长量平均数分别比对照高２０．６％，８２．１％和３３．６％，表现出明显的遗传优势；各家系苗高生长量和生长节律上有显著差异，千粒质量、场圃发芽率、抗病性和抗寒性上也都有明显差别。因此，在杉木育苗管理上应分家系或家系类群采取相应的有育苗管理措施。

| Abstract: | Ninteen primary selected half sib elite families of Chinese fir were tested on seedling growing in Jiande City,Zhejiang Province.The results showed that seed germination potential,seedling disease resistance and height increment of elite families were 20 6%,82 1% and 33 6% higher than those of control family respectively.Seedling height increment and growth rhythm of each family were of significant difference,and field germination percentage,disease resistance and cold resistance of each family seedlings were of obvious difference too.Therefore,some different management measures should be taken on families or family categories in seedling growing. |
