| Abstract | ||||
| In 2003 and 2004 seasons, mature vines of Flame seedless grapevines were pruned at the dormant season to leave 39, 54, 69 and 34 buds per vine with (1.0, 1 : <15, or 1.5 : 2 cm thickness fruiting spurs. Raising the bud load per vine was achieved by increasing number of the fruiting spurs. In this respect. increasing vine load from 39 to 84 buds was accompanied with improving fruiting buds %, yieldivine, number of clusters per vine, total acidity %, total carbohydrates, CfN ratio and reducing the shoot length, shoot base diameter, leaf area, pruning weight, cluster weight, berry size and weight, total soluble solids%, total anthocyanin and total N %. All the studied parameters except total acidity were tended to increase with raising the thickness of fruiting spurs. A slight influence on the investigated characters was recorded between using 1 : <15 and 15:2 cm thickness fruiting spurs. The highest yield with fairly good quality of Flame grapevines was obtained with a charge of 69 buds per vine with 1 : «11.5 cm thickness fruiting spurs. | ||||
