| Abstract | ||||
| Flame Seedless and Red globe considered as most popular grape cultivars in Egypt, successfully grown under different soil and climate conditions. Under Al-Minia conditions, these two cvs., faces some problems such as poor chemical characteristics of berries especially poor coloration. In order to improving the physical and chemical characteristics of these two cultivars, field experiment was achieved, included nine treatments: Control, spraying abscisic acid or ethylene four concentrations (100 ppm, 200 ppm, 300 ppm and 400 ppm). Each treatment was replicated three times, one vine per each. All treatments were frequently applied three times. The positive effect of ABA treatments were more clear on berry physical properties “represented by berry weight and berry dimensions” than those of ethylene treatments for the two cvs. Furthermore, the response of “Red globe” cluster and berry physical properties to spraying ABA was clearer than those of “Flame seedless”. The berry chemical properties of the two cultivars significantly enhanced as a result of spraying the two examined materials (Ethylene or ABA). However, this positive effect was clearer for ethylene treatments than those of ABA. The obtained data confirmed that, non-significant differences were observed between the two higher concentrations neither for physical properties nor for chemical properties | ||||
