520 _aThe morphology and anatomy of abortion at the ear top of maize were studies. The results showed that all pistillate florets silked before pollination at the ear top could develop with complete and maturity embryo sacs, similar to those of the middle and lower florets, although they were smaller than the latters. After pollination, however, their endosperms and embryoes developed and differentiated differently with the normal ones in beginning later and stopping earlier, less endosperm cells, starch grains and embryonic primordiums and smaller embryoes. The main cause of abortion was their poor competition abilities for nutrients with
