摘要
福建省华安利水国有林场,对来自广东、广西等不同种源地的火力楠8个种源77个家系子代林的树高、胸径、保存率等指标进行测定与分析。结果表明:3年生火力楠的保存率在不同种源、家系间差异均不显著外,树高、胸径的不同种源、家系间均存在极显著差异。以来自广西浦北和钦州的天然种源6、7表现最优,其次是广西凭祥次生种源8,最差的为来自广东云浮次生种源3;家系99、89、82、78、65、47,这6个家系在生长表现和保存率上均优于其他家系。说明2个天然种源、6个家系在福建华安表现较好。可为今后火力楠的良种选育提供参考。
This study analysised the growth and survival of 3 years old Michelia macclurei plantation of 8 provenances 77 families from Guangdong and Guangxi Provinces in South Fujian. The results show that there have significant differences on tree height, DBH among different provenances and families. The provenance 6 and 7 were performed best on height and DBH, which from Pubei and Qinzhou in Guangxi Province, and the second one was provenance 8 from Pinxiang in Guangxi, but the poorest one was provenance 3 from Yunfu in Guangdong Province which belong non-natural provenance. Based on analysis family level, family 99,89,82,78,65 and 47 were significant better than other families on growth and survival. In a work,there have 6 families from 2 natural provenances were optimum for plantation in South Fujian, this study would provide technical support for M. macclurei tree breeding and forest construction in the future.
