Abstract:
The acetolyzed pollens and spores of 60 genera and 80 species belonging to 37 families of mangrove species in Thailand have been examined by light microscope and scanning electron microscope. The pollens and spores can be divided into 53 pollen and spore types and 22 subtypes based on characteristic of apertures, size, shapes and ornamentations etc. The correlation between tectal characteristic and abiotic factors in mangrove habitats is still obscure. But the result from this study suggests that pollen grains of mangrove species seem to have closed tectum. Moreover, the constructed key to pollen and spore types, the pollen and spore type descriptions, and permanent slides of pollen and spores can be used as a tool to identify plant species for pollen analysis of mangrove sediment in Thailand.
