Abstract: Pollen wall is a key component of a pollen and plays an important role in pollen development and fertilization. Many courses related with the development of the pollen wall are identified in the study of male sterility,for instance,the degradation of tapetum and callose,the formation and degradation of the primexine as well as the development of a pollen intine,present the special relationship with the male sterility. In this paper we summarize the development of pollen wall based on the the reports of male sterility,aiming at discovering the general pattern in the development of pollen wall as well as providing a theoretical support in studying functional and dissecting mechanism of pollen wall in male sterility.

Key words: male sterility, pollen-wall, tapetum wall, callose, primexine
