| Abstract: | The developmental process of ear in maize have been examined by using SEM,TEM and optical microscopes. The female flowers develop on the short branches known as ears. The developmental process of ear passed through asexual, bisexual and unisexual stages. The produces of unisexual flowers were due to the result of selective abortion of stamens. Vacuolation occurred in the cells of abortion stamens primordia in the ear, and then the organelles disappeared. The protoplasm in abortion cells were translocated mainly by multivesicular bodies. |
