Studies on Growth and Differentiation in Cultured Cells of Rice (Oryza Sativa)
Callus induction and regeneration in rice (Oryza sativa) has been demonstrated by many workers (1). This capacity, however, declines with age of the cultures (4). Keeping in view the stimulatory effect of low doses of ionizing radiation on regeneration of plants from callus cultures (5), (6), we used gamma irradiation on old calli of rice which exhibited low potential to organize shoots. This communication deals with the effects of gamma irradiation on growth and differentiation of an old cell line of rice.
