Abstract:
This paper deals with the pollen morphology of 22 species of the aquatic plants belonging to 18 genera and 13 families. 11 species of them are first time reported: Potarnogeton maackianus Benn; P. malaianus Miq., MyriophyUurn spicatum L., Zizania latifolia Turcz., Sagittaria sagittifolia L. var. longilaba Turcz., Polygonum hydropiper L., Ranunculus sceleratus L., Cardamine lyrata Bunge, Cyperus difforrnis L., Eleocharis pellucida Presl and Scirpus rnucronatus Diels. All pollen grains were observed under light microscope (LM) but 12 species among them were also examined under scanning electronic microscope(SEM). The environmental conditions and community structure of aquatic vegetation in the lake are briefly discussed.
