Abstract

• Pollen morphology of 14 mangrove species belonging to 10 genera of 9 families were studied, classified and identified by available literatures. Pollen of 14 mangrove species (Nypa fruticans, Ticantio crista, Kandelia obovate, Excoecaria agallocha, Sonneratia apetala, S. caseolaris, Sesuvium portulacastrum, Aegiceras corniculatum, A. floridum, Vincetoxicum flexuosum var. tenuis, Acanthus ilicifolius, Avicennia alba, A. marina, A.officinalis) were observed with a binocular electric microscope. Pollen study area is in Yae- chan- pyin village, Kyauk- tan village, Aung- mingalar village, Nar- yae- kan village and along the Sittway costal, Rakhine State. The pollen key to the species has been constructed based on the acquired palynological assessment. Pollen of all the species have been recorded with aperture number, position, shape, size, and sculpture of the exine; investigated species were pollinia and monads; varying form porate, colporate, colpate to sulcate. The equatorial and polar views of each taxon were recorded by photomicrographs. The present study revealed that the pollen morphology of some mangrove species in study area. Mangrove pollen is crucial for the reproduction of mangrove trees, which are key components of coastal ecosystems. These trees provide habitats for numerous species, contributing to biodiversity. Therefore, the pollen morphology of mangrove plants needs to be protected and regularly assessed.
