    • Abstract
  • The formation and developmental process of pollen and fundamental structure and development of anther wall in sterile plant and fertile plant of PXDGMSR were studied in the thesis.The main reasons of pollen abortion of sterile plants are:(1)Tapetum cell delayed disintegration.(2)Pollen mother cell formed coenocyte when the meiosis of pollen mother cell is simutaneons type.(3)The meiophase cell vacuolated abnormally,chromosome adhered,spindle formed irregularly,cell nucleus vesiculated when meiosis of pollen mother cell is successive type.
