| Abstract | ||
| This investigation was carried out in a private vineyard located at Baramon Horticulture Station, Dakahlia governorate, to disclose the effect of leaf number on growth, yield and bunch quality of Ruby Seedless grapevines. Vines were ten-year-old and trained to the bilateral cordon system. The treatments were applied after fruit set as follows: 16, 14, 12, 10 and 8 leaves per shoot. The results showed that slight removal of leaves leaving sixteen leaves/shoot gave the best results as compared to the severe removal of leaves leaving eight leaves/shoot. This treatment can be considered as an appropriate practice for achieving the best vegetative growth parameters, the highest yield and its components as well as improving the physical properties of clusters and increasing berry colouration and TSS%, while decreasing the acidity% of the juice. | ||
