USE OF THE REST AVOIDANCE TECHNIQUE IN PEACHES IN ISRAEL |

| Abstract:
'Earligrande' peach trees grown in the intensive-meadow orchard system were protected against hail by hail nets. Bud break was obtained prior to exposure to chilling by using the rest avoidance technique. A combination of withholding water, followed by chemical defoliation and by a chemical rest breaking treatment led to good leafing and bloom. When trees were treated at the right time, normal fruit developed. Best rest-breaking agents were a combination of KNO3, oil and DNOC, or 1% hydrogen cyanamide. Foliage cover was too little to support the developing fruit in winter, due to rosette formation. A second, normal, bud break occurred after rest completion in late January that produced a second bloom and markedly increased leaf area. A second crop was obtained that ripened in the normal period of early May. The responses to rest avoidance treatment in the tropics vs. the subtropics are compared. | |
