【摘要】 研究了采自福建九龙江口龙海县浮宫镇草埔头村(24°29′N,117°55′E)的3种红树植物——桐花树(Aegicerascorniculatum)、白骨壤(Avicenniamarina)和秋茄(Kandeliacandel)的叶片结构及其生态学意义。这3种红树植物叶片结构中,都具有适应海滩环境的结构——较厚的角质层,表皮之内有内皮层,内皮层是贮水组织的一种。3种红树植物的叶片结构表明,秋茄具等面叶,桐花树和白骨壤是异面叶。从3种红树植物叶片横切面的染色状况可判断,3种红树植物的单宁含量,秋茄最高,桐花树第二,白骨壤最少。更多还原

【Abstract】 The anatomy of the leaves and its ecological adaptation of three species of mangrove plants—— Aegiceras corniculatum, Avicennia marina and Kandelia candel were studied. They are collected from Fugong village, Longhai , Fujian(24°29′N,117°55′E).Their relatively thick cuticle and hypodermis in leaf structure of three species of mangrove plants make them adapt to the environment of foreshore, and hypodermis is aqueous tissue. K. candel showed isobilateral leaf structure and the remaining two species dorsiventral. It can be referred that according to the degree of stained and tannin distribution in different tissues of leaf, the tannin in K. candel is most, that in A. corniculatum is second, that in A. marina is least among three species of mangroves.更多还原
