Abstract: The nuclear-free Litchi is a more valuable variety in Litchis. It has rich spurious seed' coat, more of the seeds have degenerated, so it belongs to the small putamen type. In the course of the embryonic development, after the microspore tetrad is formed, although some forms of the microspore were under developed, and lose of protoplasm, but some have formed normal microspore. Yet the megaspores have all kind of degenerated forms in all developmental phases, so it can' t form the embryo, this is the main reason of forming small putamen type. Starch accumulation and dispersion are in possession of the important function to the development of embryo sac and male gametophyte. On the other hand, the dynamic characteristic of starch in nuclear-free Litchi is similar to handing-green Litehi.
