1016	Nwe Oo	COMPARATIVE MORPHOLOGICAL AND HISTOLOGICAL STUDIES OF TALINUM TRIANGULARE (JACQ.) WILLD. AND TALINUM PANICULATUM (JACQ.) GAERTN. (MYANMAR GINSENG)	Talinum triangulare (Jacq.) Willd. (waterleaf, Ceylon ginseng or leaf ginseng) and T. paniculatum (Jacq.) Gaertn. (fame flower, jewels of opar or ginseng jawa) belong to the family Talinaceae. Both were locally known as Myanmar-ginseng. Their leaves have been used as leafy vegetables and roots as medicinal purposes. These were look alike with each other but they have different botanical characters. The root of T. triangulare (Jacq.) Willd was light brown and T. paniculatum (Jacq.) Gaertn was dark brown. T. triangulare (Jacq.) Willd. can easily be distinguished from T. paniculatum (Jacq.) Gaertn.by its triangular peduncle and cymose inflorescence (terete peduncle and paniculate cyme in T. paniculatum (Jacq.) Gaertn). The fruits of T. paniculatum (Jacq.) Gaertn were colorful like jewels while the fruits of T. triangulare (Jacq.) Willd were creamy white with reddish spots and persistent sepals. By using the methods of Trease and Evans (2009), their common histological characters were found as the presence of paracytic stomata, starch grains, calcium oxalate crystals and mucilages in leaves, stem and root. T. triangulare (Jacq.) Willd. can be differentiated from T. paniculatum (Jacq.) Gaertn. by the presence of triangular outline young stem, presence of papillae and rounded xylem vessels.	2020

1019	Myat Thwe Myint Aung	DETERMINATION OF NITROGEN FIXING RATE AT THE RHIZOSPHERIC SEDIMENT OF MANGROVE FOREST IN SHWE THAUNG YAN MANGROVE FOREST, MYANMAR	Mangrove forests dominate the world's tropical and subtropical coastlines, and provide a unique ecosystem. Mangrove sediments play a critical role in biogeochemical processes by behaving as both source and sink for nutrients and other materials. The interactions of mangrove plant�s growth rate and the sediment nutrients are complex and dynamic. Nitrogen fixation is a process that converted the atmospheric nitrogen gas to ammonium and it is an important source of new nutrient in the mangrove ecosystem. However, the study of nitrogen fixation rate in rhizospheric sediment of mangrove forest is rare, and the factors that regulate N fixation within the biome remain largely unknown. In this study, the rate of nitrogen fixation in mangrove sediment was investigated using the acetylene reduction technique. Sediment samples were collected from Shwe Thaung Yan mangrove forest and were calculated the nitrogen fixation rate. The differences between sediment depths and nitrogen fixation rate, and nitrogen fixation ability at the mangrove forest were described.	2020
