    Taxonomic Investigation of Some Members of Fabaceae (Subfamily- Caesalpinioidae) With Special Reference to Pollen Morphology
    (University of North Bengal, 2020-03) Mondal, Swarnaditya; Roy, Biswajit; Bhandari, Jnan Bikash
    Palynology, the study of pollen, had a big role in taxonomic identification, paleontology and forensics. Pollens from different plants had different morphology, such as in Fabaceae. This study aimed to determine the pollen grains morphology in Fabaceae (Subfamily Caesalpinioidae). Pollen morphology of 19 plant species under 7 genera Fabaceae (Subfamily Caesalpinioidae) were examined. Fresh pollen samples were collected from 4 plant species from the North 24 Pgns, 2 plant species from South 24 Pgns, 8 plant species from Kolkata, 2 plant species from Nadia and 3 plant species from Howrah. Pollens were acetolysed following standard method and observed under Compound microscope. Pollen shapes were recorded based on the P/E ratio. In general, all these pollens were small, medium and large size. Parameters measured in this study were the types of pollen sizes, pollen shape, aperture characteristic, and ornamentation type of exine and the most common aperture type was tricolporate. The most important characters included exine ornamentation (exine ornamentation type) and Apocolpium Index.
