| Abstract: | The effect of RENO3 on the rapid propagation of the Cerasus mahaleb seedlings in test tube was studied by investigating the growth and physiological aspects of Cerasus mahaleb seedlings propagated from stems in MS medium supplemented with RENO3 （ 5 - 20 mg/L）. It was concluded that RENO3 promoted the growth of the seedlings by in- creasing the shooting numbers and the fresh weight and height of single plantlet. The activities of SOD, POD and the con- tent of chlorophyll were enhanced by the supplement of RENO3 in the medium. The optimum RENO3 supplement con- centration for the raoid seedling propagation from Cerasus mahaleb stem was 20 mg/L. |
