Abstract: The techn iques o f cutting propagation ofP otentilla f ruticosa was studied. The tender stem cuttings and thew oody stem cu tt ings w ere treated by d ifferent concentrations o f BBA ( 0 mg? kg-1, 10 mg? kg-1, 50 mg? kg-1,100mg? kg-1, 200mg? kg-1, 500 mg? kg-1 ) . The resu lts ind icated that the roo ting percen tage o f tender stemcuttings at the concentration of 10mg ? kg- 1BBA w as the h ighest ( 88. 3% ) , and that ofw oody stem cutt ings treated by the concentration o f 50 mg? kg-1 BBA w as the h ighest( 66. 67% ). It also ind icated that the roo ting percentages of the tender stem cuttingsw ere better than those of the woody stem cuttings w ith same treatmen.t
