| Abstract | ||
| This investigation was carried out during the three seasons of 2005, 2006 and 2007 in a private vineyard located at EL-Khatatba district, EL-Monofia Governorate. For this study, Superior Seedless grapevines (Vitis vinifera, L.) were used as source of scions and four rootstocks, Teleki 5C, Paulsen 1103 and SO4 (American stocks) besides of the control (own-rooted). The following determinations were carried out : bud behaviour, average leaf area, yield per vine, physical and chemical characteristics of bunch and berries. The data reveal that, most of rootstocks increased N, P, K contents in the leaves and total carbohydrates in the canes. The results also showed that bud burst, bud fertility and leaf area of Superior seedless grapevine on Telelki 5C rootstock gave a higher value than the other rootstocks or the control. Superior on Teleki 5C rootstock increased the yield per vine, cluster weight and number of berries per cluster as compared with the other rootstock or the control. Vines grafted on Paulsen 1103 or Teleki 5C increased berry weight, size and juice volume compared to other treatments used. Whereas, the control gave the lowest values in this respect. Superior own rooted (control) generally resulted a higher percentages of SSC, SSC/acid ratio and lower acidity in berry juice than the other rootstocks used. The highest value of carbohydrate in canes was observed in the vines rooted on Teleki 5C, Paulsen 1103 or SO4 than the control. Whereas, N content in the leaves of Superior in own rooted was higher than other rootstocks used. Furthermore, the content of P in leaves of Superior on SO4 and Paulsen 1103 rootstocks were higher than the other Teleki 5C rootstock or the control. Whereas, there is no significant differences in potassium content in leaves between the rootstocks used or the control. | ||
