Influence of different fruiting shoots ratios on productivity attributes and fruit quality of ruby seedless grapevines in the current and following seasons [electronic resource].

Includes references.

Field experiment was conducted during 2007/2008 and 2008/2009 seasons on 7-years old grapevines cv. Ruby Seedless grown in clay soil located at Dakahlia governorate, Egypt and irrigated by drip irrigation system. Vines were spaced at 2.5 x 3 meters apart, pruned during the first week of January. A bilateral cordon was used as a training system with 40 buds / vine. Treatments were imposed on different vines in both years, and follow up the residue effects in the next season on bud behavior, yield weight and fruit quality. Seventy five vines were used and divided into five groups (fifteen each) according to fruiting shoots ratio to reach the best ratio between fruiting and vegetative shoots to achieve not only maximum productivity with high fruit quality in the current season but also in the following season as well.
