福建柏初级种子园不同家系半同胞子代生长比较分析

The Comparative Analysis on Different Pedigree half Compatriot Filial Generation Growth in Fokienia Hodginsii Primary Seed garden

以福建柏初级种子园作为研究对象,跟踪调查种子园不同家系的生长情况,结果表明:不同调查年份、不同福建柏家系生长情况表现差异较大,其中1号、4号、18号、36号及38号福建柏家系生长量较大、稳定性较好,可作为优良家系。方差分析结果表明:在幼林生长初期(1a生及2a生),各家系苗高与地径生长指标与混合种子代相比差异达极显著水平;在幼林生长中后期(3a生及5a生),差异性逐渐降低。

The primary seed orchard of Fokienia hodginsii was acted as the research object,the seed orchard＇s different genealogy growth situation were investigated in this paper. The results showed that different vintages survey of Fokienia hodginsii growth performance was very different,including 1,4,18,36 and 38 Fokienia Hodginsii genealogy growth was bigger than the others,the stability was also better,and can be used as a fine pedigree. The results of variance analysis showed that,in the early growth of young forest （1 year and 2 years）,the growth index of different genealogy＇s height of seeding and caliper compared with horizontal have a significant difference,After young growth period （3 years and 5 years）,the difference gradually reduced.
