Abstract:There is a close relationship between the change (increase or decrease) of polysaccharide, lipid and protein with the suppliment of nutrition during the development of pollen. The polysaccharide disapper from the wall layers gradually during the stage of meiosis. There is a great deal of lipid in the early stage of pollen mother cell, but there is neither amyloplastid nor protein grain showing. In the pollen mother cell the middle layers and tapetum accumulated a great deal of protein and lipid during the early stage of pollen mother cell, but there is neither amyloplastid nor protein showing. The middle layers and tapetum accumulated a great deal of protein and lipid during the stage of meiosis. Having finished meiosis the amyloplastid and lipid begin to appear in the tapetum and microspore tetrad, and the protein is induced. In the stage of microspore, there is a great deal of amyloplastid around the nuclear of microspore, and lipid is deposited on the wall of microspore and the radial, and on the endoscopic wall of tapetum cell. Meanwhile, the protein grain is not observed.
