Leaf structure and its ecological adaptability in three species of mangroves

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.
