INFLUENCE OF CANOPY MANAGEMENT PRACTICES ON YIELD AND BERRY QUALITY OF RUBY SEEDLESS GRAPEVINES UNDER DAKAHLIA GOVERNORATE CONDITIONS.
This study was carried out during 2002 and 2003 seasons on Ruby Seedless grapevines to examine the effect of removing the basal leaves at bloom or after fruit set each alone or combined with shoot thinning and topping or bolh on yield. cluster characteristics as well as berry physical and chemical characterislics. All canopy management practices which contained leaf removal after fruit set with or without shoot thinning and topping increased pack.able and totat yield per vine. cluster weight. compactness coefficient and juice volume. whereas the percentage of cull yield was decreased than the control. On the other hand. early removal of the basat leaves alone or combined with shoot thinning reduced total yield. cluster weight, berry weight and juice volume than the control. Canopy management practices of leaf removal after fruit set plus shoot thinning and topping gave a higher yield. cluster weight. berry weight and juice volume than the other treatments and the control. Cluster and berry length were not significantly affected by Ihe above canopy management treatments. All canopy management applications increased T.S.S .• T.S.S.lacid ratio, anthocyanin and total reserved carbohydrates in the new canes and decreased the total acidity than the control.
