Cytomixis in pollen mother cells of Papaver dubium L.

CYTOLOGIA, 1988
Cytomixis was recorded during microsporogenesis in Papaver dubium L., a member of the family Papaveraceae. The phenomenon was observed in all the stages of meiosis. Further, it was found that not only the frequency of cytomixis but the amount of chromatin transferred reduced with the advancement of meiosis. The pollen fertility was found to be affected
