摘要
本文记载了洪湖主要水生维管束植物的花粉形态13科18属22种,其中有11种为首次报道,除对全部花粉形态进行了光学显微镜观察外,并对其中11属12种进行了扫描电镜的观察,同时也简述了它们的生境及水生植被的群落结构。
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: Potamogeton maackia- nus Benn; P. malaianus Miq., Myriophyllum spicatum L., Zizania latifolia Turcz., Sagittaria sa- gittifolia L. var. longilaba Turcz., Polygonum hydropiper L., Ranunculus sceleratus L., Car- damine lyrata Bunge, Cyperus difformis L., Eleocharis pellucida Presl and Scirpus mucrona- tus 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 con- ditions and community structure of aquatic vegetation in the lake are briefly discussed.
