Abstract: | To determine the effect of electric vibration on the growth, yield and fruit quality of peach electric vibrators that provided intermittent perturbation of 6500 rpm for 15 min every 6 h were firmly attached to the trunks of peach trees. Electric vibration resulted in the reduction of shoot length by 80% but had no significant effect on fruit weight, acid content and Brix. In another experiment, electric vibrators (for 15 min every 2 h) were attached to the branches after summer pruning. The regenerated shoots from the treated branches showed more than 500% reduction in length compared to the untreated ones. Even the regenerated shoots of untreated branches nearby the vibrator showed 60% reduction in length. Ethylene production and ACC content in the shoot tips of treated branches were greater than that from control ones. |
