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0.6819、0.7556、0.5137、0.7994,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.
為瞭選擇適于閩北地區種植的烏桕種源,研究以24份種源(來自6省份)為試材進行瞭烏桕引種造林試驗.結果錶明:不同種源烏桕的地徑、樹高、單序果數、韆粒質量、單位麵積種子產量、種子含油率性狀均存在極顯著的差異.烏桕單序果數、韆粒質量、單位麵積種子產量、種子含油率等主要經濟性狀種源遺傳力分彆為0.6819、0.7556、0.5137、0.7994,具有明顯的種源效應;烏桕種源的地徑、樹高生長錶現為水平地理變異模式,單序果數、韆粒質量、單位麵積種子產量、種子含油率等經濟性狀均錶現為隨機變異模式.參試的24箇種源,經穩定性分析和聚類分析,可劃分為4箇種源類彆:Ⅰ類種源(優良種源)、Ⅱ類種源(可利用種源)、Ⅲ類種源(一般種源)、Ⅳ類種源(較差種源).Ⅰ類種源 WJ-02(福建浦城)、WJ-19(湖北大悟)為2箇優良種源,在經濟性狀綜閤錶現上具有明顯優勢,且適應性彊,遺傳穩定性高,適用于福建閩北烏桕經濟林、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.
