| To control sprout growth induced by severe pruning of old pomegranate trees (Punica granatum L.), NAA at 0.25, 0.5, and 1 percent and MI-I at 6,7.5, and 10 percent levels were used in 2 separate experiments: in the first experiment, at the time of pruning, NAA and MH at above concentrations were applied to the pruning cuts as a solution or in mixture with a pruning wax. In the second experiment, NAA and MH were used at above concentrations, but for complete control of sprouts, the pruning cuts were treated once at the time of pruning and again 3 months later. Results obtained from these sxperiments indicated that 1 % solution of NAA reduced sprout number for the first 3 months and sprout elongation was also reduced at 0.5 and 1 % NAA. Sprout control was obtained with mixture of NAA+ Wax at 1 %. MH at 7.5 and 10 % solution was effective i&reducing the number and length of sprouts while MH+ wax was effective only at 10%. The inhibitory effect of NAA and MH solutions on sprout growth during the second year was significant at 1 and 10 % respectively, but during the third year, there were no significant differences in sprout growth between the treated and control plants. In the second experiment, when NAA at 0.5% and 1% and MH above 6% were applied twice, sprout growth was complety inhibited. | ||
