Effect of bud loads on mechanical composition of cluster and chemical content of must in Victoria table grape variety (Vitis Vinifera L.)

The two-year experiment (2008 and 2009) on new introduced table grape variety Victoria was carried out in the commercial vineyard in the conditions of Nerezi vine district, Capljina Municipality. This study the influence of different bud load levels was investigate on grape quality of cv. Victoria under given environmental conditions. The experiment was conducted by random selection method in four variants with different bud load levels per grapevine (19, 24, 28 and 33 buds per grapevine), each variant being repeated four times with 6 vines repeating. Variant II(24 buds per grapevine) had, in two-year experiment, the average value of the largest cluster weight (599.78 g), the cluster berry weight (573.25 g), and the mass of the cluster stems (12.5 g). The average content of sugar in the grape must was slightly higher in variants I and II (14 %) compared to other variants, while the highest average content of total acids had variant III (4,06 g/l).
