Abstract

The development of ovule and female gametophyte in Liriodendron chinense was observed by means of conventional methods. The ovule is anatropous, consisting of bitegmy ,crassinucellus, nucellar beak and hypostase. The type of embryo sacbelongs to the polygonum one. Mature embryo sac is narrow with inflate ends. The egg cell is roundish with an unobvious polaritical nucleus. The two polar nuclei don t fuse until one sperm get attached.And the antipodal cells degrade. During the development , the starch grains accumulate centripetally. This paper of fers the relationship between the development of ovule and female gametophyte and the length of the flower bud, and discusses the relationship between the development and seeding rate.
