The effects of girdling and ethephon treatment on ripening and yield quality and fruit characteristics of buhurzy grape cultivar vitis vinifera l


, : The effects of girdling and ethephon treatment on ripening and yield quality and fruit characteristics of buhurzy grape cultivar vitis vinifera l. Annals of Agricultural Science (Cairo) 34(1): 675-688

The research was carried cut in the Al-Zaafraniyah Horticultural Experiment Station, for 1987 and 1988 season, to study the effect of girdling and ethephon treatments on ripening and fruit characteristics of Buhurzy grape cv. (Vitis vinifera L.). The results showed that ethephon 1000 ppm and the combination of (girdling + 1000 ppm of ethephon) were found to be most effective treatments in advancing fruit ripening by 7-8 days as compared to the control. These treatments showed a high significantly total yield per vine; cluster weight; weight of 100 berries in 1988 season. TSS increased and acidity decreased significantly in both seasons by ethephon. Girdling resulted in advancing fruit ripening 3-4 days as compared to the control.
