摘要
该试验为世界银行贷款国家造林项目第一期工程（ＮＡＰ）之科研推广计划中的阔叶树试验内容。报告对木兰科鹅掌揪属的２个种和１个人工杂交种即鹅掌揪（马褂木）、 北美鹅掌揪、杂交马褂木共１７个种源进行了育苗试验，２０个种源进行了造林试验。对１年生苗高生长及造林后１、２年生的树高及年度高生长量进行了测定，对各种源苗期、１年生、２年生幼林高生长进行了对比及方差分析。测定结果初步表明各种源间的高生长存在着显著的遗传差异。
Abstract The broard - leaved forest test in this paper is in the research & development programme forNational Afforestation Project (NAP) Which is credited by World Bank. 17 germ plasm resources ofLiriodendron Chinense (Hemsl. ), Liriodendron Tulipiferal., Liriodendro Chinense XL. Tnlipifera, i. e. 2Species of Liriodendron,Magroliaceae were raised seedling test, 20 germ plasm resources were afforested test.lage seedlings growth in length, lage or2 age plantlets growth in length and their growth rhythm weremeasured, compared each other and data analysis of variance. Preliminary tested result showed that theirgrowth in length were significant difference among these germ plasm resources. The significant differencewas gradualy changed smaller till stability from seedling stage to plantlet stage, But it still showed significantdifference.Subject words: Liriodendron Chinense (Hemsl. ), Giological germ plasm resource. Seedling stage. Plantletstage, Growth in length
