Abstract:Using TEM,SEM,and traditional paraffin section,we studied the process of megasporogenesis and microsporogenesis and the development of female and male gametophyte of Shibataea chinensis.The anther wall consisted of four layers.They were epidermis,endothecium,middle layer and tapetum.The development of anther wall belonged to the monocotyledonous type.The tapetum is glandular.The cytokinensis was successive and the microspore tetrads are bilaterally symmetrical.Most mature pollen grains are 2-celled with one germinal aperture.The simple ovary consisted of two carpels.Single ovule with parietal placenta was anatropous,double integument and tenuinucellatae.The megasporocyte underwent meiotic division to form four megaspores arranged in a line,and the micropylar megaspore was the functional one.The reason for the no seed-setting rate is discussed.
