Present experiment has been carried out in order to make clear the abnormalities of the female gametophyte formation and its relation to fertility, using the short-style of F. koreana, the results of which are summarized as follows :
(1) Anatropous ovule has single integument with thick cell-layer and tiny nucellus consisting of nucellaepidermis and megaspore mother cell.
(2) Meiotic division of megaspore mother cell takes place around middle or latter part of March, while that of microspore mother cell occurs from the end of September to the beginning of October.
(3) Megaspore mother cell stage is long, and ranges from October to March next year.
(4) Formation of mature embryo sac is not completed until the beginning of May, approximately one month after bicoming.
(5) Normal embryo sac is rare, most of the nucellus being devoid of embryo sac.
