摘要
为了选择适于闽北地区种植的乌桕种源,研究以24份种源(来自6省份)为试材进行了乌桕引种造林试验.结果表明:不同种源乌桕的地径、树高、单序果数、千粒质量、单位面积种子产量、种子含油率性状均存在极显著的差异.乌桕单序果数、千粒质量、单位面积种子产量、种子含油率等主要经济性状种源遗传力分别为0.681 9、0.755 6、0.513 7、0.799 4,具有明显的种源效应;乌桕种源的地径、树高生长表现为水平地理变异模式,单序果数、千粒质量、单位面积种子产量、种子含油率等经济性状均表现为随机变异模式.参试的24个种源,经稳定性分析和聚类分析,可划分为4个种源类别:Ⅰ类种源(优良种源)、Ⅱ类种源(可利用种源)、Ⅲ类种源(一般种源)、Ⅳ类种源(较差种源).Ⅰ类种源WJ-02(福建浦城)、WJ-19(湖北大悟)为2个优良种源,在经济性状综合表现上具有明显优势,且适应性强,遗传稳定性高,适用于福建闽北乌桕经济林、能源林培育.
In order to choice the suitabe species of Sapium sebiferum,24 germplasm from 6 Province were planted in Fuj ian Province.The result showed there was a significant differencees among ground di-ameter,height,single order fruit number,1000 grain weight,seed yield per unit area,seed oil content from the comparative trial on 24 provenances of Sapium sebiferum.The results showed the provenance herita-bility of single order fruit number,1 000 grain weight,seed yield per unit area,seed oil content was 0.681 9,0.755 6,0.513 7 and 0.799 4 respectively,and there was significant provenance effect.The ground diameter and height of provenance showed geographic variant pattern and the parameters of fruit number, 1000 grain weight,seed yield per unit area and seed oil content performed random variant pattern.With sta-bility and cluster analysis,the 24 provenances could be divided into 4 kinds of source categories,one was WJ-02 （Fujian Pucheng）and WJ-19 （Hubei Dawu）with obvious advantages in comprehensive performance of economic traits,genetic stability and strong adaptability to be appropriate for culture of economic and en-ergy forestry in northern Fuj ian province.
