In the late of April of the second year, male inflorescences unbound and pollinated. When female inflorescences accepted the pollen grains, ovary development was increased in early May. With the development of either of the two ovule, funiculus, integument and nucellus were differentiated. Embryo sac mother cell came into being and the meiosis begins. Then fuctional megaspore developed into matured embryo sac that contain eight nucleuses. In the end of May, double fertilization generated.

Megaspore development and abortion of"Pingyi Tiancha"Compar-ing with regular developing megaspore of normal M.baccata,the megasporemother cellof"Pingyi Tiancha"could form mono-nucleus embryo sacby perhaps irregular meiosis,then most of sexual MES depauperatedand degenerated,finally aborted,or only a few further developed.Of asexualembryo sac,one or more large cells at the chalazal end of nucellus developed in-to one to more asexual embryo sac initials.After the competition between sexu-al embryo sacand asexual embryosac,most ovules only had one asexual embryo sac matured.
平邑甜茶大孢子的发育和败育与正常发育的山定子大孢子对比,平邑甜茶大孢子母细胞经减数分裂能形成单核胚囊,之后多数有性胚囊萎缩、退化而败育,只有极少数进一步发育;而无性胚囊则从胚珠合点端1个或多个较大的珠心细脆形成并首先发育为一个或多个无性胚囊原始体;经过有性胚囊和无性胚囊以及无性胚囊和无性胚囊之间的竞争,多数胚珠只有一个无性胚囊成熟。

These results revealed that the pollen chamber developmental pattern passed through four phases. Firstly, a group of nucellar cells at the micropylar end elongated longitudinally. Thereafter, the uppermost nucellar cells at the micropylar end initiated PCD; and these elongated cells undergoed PCD in a basally and laterally oriented direction to form a cavity.
