Combinations of ancymidol and chlorethephon on growth and rooting of balsam (Impatiens balsaminaL.)

Effects of 4 rates each of ancymidol and chlorethephon applied in factorial combination as drenches were measured on plant height, leaf number and size, and rooting of balsam. All treatment combinations reduced plant heights except the low rate of each chemical (0.25 mg/pot ancymidol and 10 mg/pot chlorethephon) applied singly. Leaf number was unaffected by treatment, but leaf size was reduced. Rooting, as measured by fresh weight, was improved by increased chlorethephon rates, and ancymidol at 0.25 mg/pot. However, increasing rates of ancymidol negated the root stimulation by chlorethephon.
