Abstract:A study on the structure of mature anther and pollen grain of rioe is conducted with both GMA and Epon 812 semi-thin sections by using light microscope; meanwhile, the compositions of wall materials and ergastic substance of cells are tested with different histochemical methods. The isolated tapetal membranes are studied by using both light microscope and electron microscope. It is demonstrated that anther wall and pollen wall of rice have the general characteristics of Gramineae. There are silicious grains...
