Abstract:The development process of microsporogenesis and male gametophyte of Lycium barbarum L.NQ-2 using normal paraffin method were studied.The results showed that the anther wall developmentl belongs to the dicotyledonous type and it's composed of 4 layers,which were epidermis,endothecium,middle layer and tapetum,the tapetum was not only dual in origin but also dimorphic,belongs to secretory tapetum.Meiosis of pollen mother cells was simultaneous type,tetrads were tetrahedral.There were three colpi on the extine...
Keywords:Lycium barbarum NQ-2  microsporogenesis  male gametophyte
