摘　　要：分析了北移种植在福建省霞浦、连江、泉港、集美、漳浦5个样地无瓣海桑(Sonneratia apetala)的存活率、株高、根长、冠幅、生物量及生物量分配,结果表明:无瓣海桑人工引种北界在26°47′N～26°16′N之间,且存活率随着纬度的增高而降低;各样地无瓣海桑营养器官的含水量为:叶>根>茎,其含水量均值分别为86.4%、71.0%、63.0%,植株有机质在根茎叶器官分配为茎>根>叶;根部的长度和重量随着纬度的升高而下降;株高、冠幅随着纬度的升高有所变化,但没有显著性差异.The survival rate, plant height, root length, crown width, biomass and biomass allocation of north-introduced Sonneratia apetala, which has been transplanted in Xiapu, Lian river, Quangang, Jimei,Zhangpu of Fujian provience, are analyzed. The results show that the boundary of artificial introduction of Sonneratia apetala to the north is in the range from 26o47＇ N to 26016p N, and the survival rate decreases as the latitude increases; the water content of different plant organs is stem〉 root〉leaves,with 86.4o/60,71.0~, 63. 0% respectively; the allocation of organic matter is stem〉 root 〉 leaf; root length and weight decreasing with increased latitudes; plant height and crown width changing as the latitude decreasing, but the difference is not obvious.
