| 摘 要： | 笔者以湖北省京山县鹅掌楸属种源试验林2个树种鹅掌楸与北美鹅掌楸共20个种源为对象,进行了14 a时的生长和主要木材性状的研究。结果表明:北美鹅掌楸的生长优于鹅掌楸,而木材性状则不及鹅掌楸。在胸径、树高、材积、基本密度和纤维长度5个测试性状中,各种源之间存在显著或者极显著差异,为优良种源的选择奠定了基础。相同试验材料不同试验点的结果存在较大分歧表明:鹅掌楸受到较强的环境因素影响,因此在进行种源选择时必须加以考虑。

| Abstract: | Provenance forest composed of 2 species 20 provenances of Liriodendron chinese（Hemsl.） Sarg.and Liriodendron tulipifera L.in Jingshan County in Hubei Province was performed.Growth and main wood characteristics of 14-year-old stand were investigated.Liriodendron tulipifera Linn.outperformed Liriodendron chinese（Hemsl.） Sarg.in growth traits,but underperformed in main wood characteristics.Significant differences were found among provenances in DBH,height,volume,basic density and fiber length.The same materials in different sites differed greatly,which indicated that gene×environment interaction must be considered in provenance selection. |
