EFFECTS OF SOME GROWTH REGULATORS ON THE DEVELOPMENT AND RIPENING OF PEACH FRUITS |
| Authors: | F. Gyuró, M. Dávid |
| Abstract:
On peach cv. Marygold, spraying with 5000 ppm SADH and related compounds at the stage of rapid initial growth reduced shoot length by 4–18% and encouraged earlier and more uniform fruit ripening. The most effective results followed an application of an SADH-Ethrel mixture sprayed at stone-hardening. This gave only 6.5% unripe fruit at harvesting, compared with 11% in the control. Succinic acid at 2000 ppm showed results similar to those of SADH. | |
