Pollen morphology, viability and germination of Elaeocarpus munroii (Wight) Mast., An Endemic tree species of the Western Ghats


Nusrin S, A K Sreekala

Elaeocarpus munroii belongs to the family Elaeocarpus is endemic to the Western Ghats. This plant is included in the red list under near threatened category of IUCN. A study has been carried on pollen morphology, viability, germination using light and scanning electron microscopy. The pollen viability was found to be 87-90% on the day of anthesis and it gradually reduced successive days after anthesis. In vitro pollen germination studies indicated that, maximum percentage pollen germination was 72% along with 2034.87µm tube length was noticed in Brew baker’s medium containing 20% sucrose. Pollen grains are isopolar, spherical to oblate spheroidal, tricolporate and 8.6±0.49 µm×8.8±0.40 µm in diameter.
