| Résumé : | The development of reproductive cells has been analysed in Nymphaea nouchali, family Nymphaeaceae, subclass Magnoliidae. Our observations on embryo sac development differ from those in the literature. Megasporogenesis results in a triad of one micropylar cell and two innermost megaspores. Embryo sacs derive from a single functional megaspore and are tetranucleate. Megasporogenesis is monosporic and of the Polygonum type, but mega-gametogenesis is of Oenothera type. |
