中文摘要：

研究了采自广东徐闻海岸滩涂的5种红树植物（红海榄（Rhizophora stylosa）、角果木（Ceriops tagal）、白骨壤（Avicennia marina）、桐花树（Aegiceras corniculatum）和榄李（Lumnitzera littorea））的叶片解剖结构,利用模糊隶属函数值法综合评价其抗逆性。结果表明：5种红树植物的叶片形成了适应海岸潮间带生境的结构,即具下生气孔,气孔密度较小;叶片和角质层较厚;形成下皮;栅栏组织细胞多层;富含单宁。种间抗逆性综合评价结果由大到小排序为白骨壤、桐花树、红海榄、榄李、角果木。

英文摘要：

We used five mangrove species leaves of Rhizophora stylosa, Ceriops tagal, Avicennia marina, Aegiceras corniculatum and Lumnitzera littorea, collected from Xuwen, Guandong, to study their leaf structural features and evaluate the stress re sistances by subordinate function value analysis. Five species were adapted to aquatic environment in structure with stomata distributed in lower epidermis, lower stomatal density and thicker cuticle. The tannin content was high in the leaf blade. By subordinate function value analysis, the stress resistance capabilities of the five mangrove species were in order of Avicennia marina〉Aegiceras corniculatum〉Rhizophora stylosa〉Lumnitzera littorea〉Ceriops tagal.
