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.en10.2478/s11756-008-0017-zinfo:eu-repo/semantics/closedAccessLeucojum AestivumAmaryllidaceaeMegasporogenesisMegagametogenesisArticle6316772Q4WOS:0002525395000102-s2.0-38349184197Q3
