[Proliferative activity of normal and tumorous plant tissues cultivated in vitro].
Proliferative pools of Helianthus tuberosus L. explants tissues were studied using autoradiography with 3H-thymidine in the course of normal growth in vitro and tumorous growth induced by Agrobacterium tumefaciens. It is determined that on the 3d or 4th day of tumorous transformation the number of cycling cells reaches 30% whereas that of normally growing explants showed 10-11%. No changes were observed in 3H-thymidine transport during this period.
