摘　　要：在开展鹅掌楸种质资源收集、保存工作的基础上,对中国鹅掌楸15个种源和北美鹅掌楸5个种源进行了不同种源幼苗物候期、生长节律、10个生物量性状等的比较、分析。结果表明:20个种源各性状间均存在差异,其多性状间存在显著或极显著正相关关系,且中国鹅掌楸与北美鹅掌楸在生物量方面存在极显著差异。多性状分析选择出湖南绥宁(SN)、浙江松阳(SY)、安徽黄山(HS)、贵州陌南(MN)为本地表现优良的种源。分析结果揭示鹅掌楸地理种源苗期主要经济性状的地理变异规律,以为适应本地栽培种源的选择提供理论依据。On the basis of the collection and preservation of Liriodendron germplasm the seedling phenology,growth rhythm and 10 biamass traits of 15 Liriodendron Chinese and 5 Liriodendron tulipifera provenances were compared and analyzed.The results showed：there were differences between the characters of 20 provenances,the characters had significant or very significant positive correlation,and there were significant differences in biomass between L.chinese and L.tulipifera multitrait analysis selected Hunan Suining（SN）,Zhejiang Songyang（SY）,Anhui Huangshan（HS）,Guizhou Monan（MN） as local good sources.The analysis results revealed the geographic variation law of the main economic characters of Liriodendron,which adapt able to local which provides the oretical basis for the selection of provenances conditions.;
