Abstract

Aegiceras corniculatum Blanco is one of  the important true mangrove species of the western coast of India. Wood as well as increment core samples were collected from trees having GBH ≥10 cm, from three sites in the western coast of India and wood anatomical features were recorded in the laboratory. The results indicate simple, alternate, diffuse porous vessels; both diffuse and scanty axial parenchyma, homogeneous type III rays, vestured pits, helical thickening, sheath cells, breakdown areas in ray cells and vessel inclusions. A comparison of ecoanatomical characters of this true mangrove species was made with its nearest upland relative belonging to the same family viz.,, Myrsinesandwicensis A. DC. In contrast to its upland relative, Aegiceras corniculatum recorded short vessels with smaller diameter, exceptionally high vessel frequency and high vessel grouping. The vulnerability and mesomorphy ratio of Aegiceras corniculatum recorded were 0.27 and 80, respectively which showed the xeromorphic nature of wood. Modification of hydraulic architecture of Aegiceras corniculatumwith respect to ecological condition might be the reason for survival towards the seaward line of mangrove succession and are hence, less vulnerable to cavitation. This causes a safer sap flow in this species.
