摘　　要：应用光镜及扫描电镜对生长在热带、亚热带海岸潮间带的 6种海桑属红树植物的次生木质部进行了解剖学研究表明 :海桑属 6种红树植物的次生木质部具有导管直径小 ,导管分布频率高 ,复孔率高 ,导管壁厚和纤维壁较厚且具次生加厚 ,木薄壁组织缺乏或稀少等与环境相适应的特点。海桑属 6种红树植物的数量特征还表明 :海桑、无瓣海桑、卵叶海桑的木材可能适合造纸。The study reveals that the secondary xylem of 6 mangrove species of Sonneratia possesses the following characteristics:the diameter of vessel is small,the distribution frequency of vessel is high,the reperforating rate is high,the wall of vessel is thick,the wall of fibre is relatively thick and the wood parenchyma is short or sparse,whish is suitable with the environment.The quantitative feature of 6 mangrove species of Sonneratia also indicates that the wood of S.caseolaria,apetalous sonneratia and ovate-leaf sonneratia is probably suitable for paper-making.
