STUDY ON MORPHOLOGICAL AND ANATOMICAL CHARACTERISTICS OF LUMNITZERA LITTOREA (JACK) VOIGT) DISTRIBUTION IN THE SOUTH OF VIETNAM
Main Article Content
Abstract
Lumnitzera littorea is the true mangroves, recorded in the Red list of IUCN 2010 with level LC and with level VU in the Vietnam Red Book 2007. This paper reports a study on some morphological and anatomical characteristics of leaves and stems of L. littorea using the method of morphological comparison, temporary double-staining microsurgery, microscope measurement, and microscope photograph on the microscope. The study aims to provide data on some morphological and anatomical characteristics of L. littorea distribution in the South of Viet Nam with different ecological environment conditions. The results showed that the stem has a thick cutincul layer, a thick hypodermis tissue layer that can increase its mechanicality, and grown xylem systems; the leaves have mesophyll cells and stomata distributed on both sides of the leaves with mature water tissue. At the same time, when comparing the leaves in three areas with each other there is a clear difference. For leaf blade thickness, leaves in Con Dao (970.39 ± 70.35 mm) are thickest, followed by leaves in Can Gio (929.06 ± 26.34 mm), and the least thick leaves were found in Phu Quoc (870.30 ± 74.84mm).
