摘 要:
采用完全随机区组设计营造了包含20个鹅掌楸种源的种源选择试验林。对13年生的种源试验林进行调查和分析，结果表明：反映纸浆林产量和质量的主要指标在种源闻均存在明显的差异，方差分析显示种源问树高、胸径和材积生长量差异达到显著或极显著的水平。利用主成分分析对20个种源进行评价，结果表明贵州黎平、松桃、陌南，浙江富阳，湖北鹤峰和美国密苏里州等地的种源为湖南低山丘陵区纸浆林最佳种源。[著者文摘]

Abstract:
The provenance trial forest which involves 20 provenance of Liriodendron was built by completely randomized design. The provenance trial on 20 provenances of 13-year-old Liriodendron was carried out. The results of investigation and statistical analysis showed that： there were significant differences in main criterions of pulp forest such as tree high, diameter at breast height and stem volume among provenances. The analyses of variance indicate there were highly significant difference in tree high, diameter at breast height and stem volume among provenances. According to the primary component analysis of the provenance trial forest, the origin of superior provenances for mountain and hill areas of Hunan were picked out, they were： Liping, Songtao, Munan GuiZhou,Fuyan ZheJiang,HeFong HuBei and Missouri USA.[著者文摘]
