Özet
In this study, gynoeceum, development of megasporangium, megasporogenesis, megagametogenesis and female gametophyte of Leucojum aestivum were examined cytologically and histologically. Ovules of L. aestivum are of anatropous, bitegmic and crassinucellate type. Inner integument forms the micropyle. Archesporial cell develops directly into a megasporocyte. Embryo sac development is of bisporic Allium type. Filiform apparatus is observed in synergids. Polar nuclei fuse before fertilization to form secondary nucleus near the antipodals.
