Abstract
This work was conducted during two successive seasons of 2004 & 2005 on ten-years-old Ruby Seedless grapevines grown in a sandy soil at El-Khatatba, Menoufiya governorate. The aim of this investigation was to study the influence of some treatments as spraying of boron at 0.2% (as Borax) at 75% bloom, GA3 at 20 ppm when berry diameter reached 2-3mm, berry thinning by retention of five shoulders at the base of the cluster with the alternative removal of the branches and removing the terminal third of the cluster at 2-3 mm berry diameter and girdling of trunk by removing a narrow ring of the bark (2-3mm) at 2-3 mm berry diameter on cluster quality, increasing yield and minimizing number of shot berries in "Ruby Seedless" clusters.. The used treatments were solitarily, double, triple and tetra combinations compared with the control treatment. Results showed that combination treatment of boron + girdling + GA3 positively increased yield / vine and cluster weight. While, the increase in cluster width, decrease in shot berries and berry physical characteristics were also increased especially when tetra combination treatment boron + berry thinning + girdling + GA3 was applied. The lowest acidity % and the highest TSS% and anthocyanine content were found in treated "Ruby Seedless" grapevines with single thinning treatment.
