[ Objective] This study deals with the relation between anther nutrient metabolism and pollen abortion of male sterile lines in Lycium barbarum L., and provides some theoretical references for the pollen abortion mechanism of male sterile lines in Lyciurn barbarurn L.. [Method] By using semi-thin section and cytochemistry technology, the accumulation and distribution of anther nutrient of male sterile and fertile lines in Lycium barbarum L. were observed and compared. [ Result] The result showed that after meiosis, starch grains in the connective parenchyma of anther decreased sharply, and starch grains in epidermis and endothecium were also greatly decreased, while nearly no lipid accumulated in tapetal cells in male sterile lines compared with the fertile lines. The tapetal cells and tetraspore had vacuoles appear successively, and then entered the degenerate process. During the degeneration stage of tapetal cells and tetraspore, starch grains in epidermis and endothecium were still in a smell number and in the connective parenchyme as well. [ Conclusion] The decrease of polysaccharide supplying in anther vascular leads to the disorder of mechanism of glycelipid transforming in tapetal ceils, which triggers the tapetal cells degenerating ahead of time, and the latter gives rise to callus wall failing to degenerate in time. Therefore, the tetrads disintegrate and disappear ultimately due to lack of nutrition.
