Influence of Irradiation during Different Development Phases of Male Generative Sphere on Embryo Processes in Cotton Plants Growing in Different Water Supply Conditions

The influence of irradiation by different doses(32)and(60)on microsporogenesis process andmale gametophyte development have beenstudied on different water supplementconditions.We have studied the pollination,fertilization,microsporogenesis and earlyembryogeny processes in Mo and FoMo.It
