The cultivated grapevine (Vitis vinifera L.) is a fruit crop of enormous economic importance with over eight million hectares planted in vineyards worldwide. Table grapes and wines represent a considerable share of the economy in many grape and wine-producing countries. The purpose of this study is to evaluate the effect of bud load on qualitative and quantitative table grapevine parameters. We study the influence of bud load by implementation of three experimental variants: 22 buds/vine, 26 buds/vine and 30 buds/vine. The experimental plant material consisted of table grapes Romanian cultivars of the Victoria and Coarna Neagra. We analyzing the influence of bud load on coefficients of fertility, productivity indices, sugars accumulation in berries grape, titratable acidity of must (g L-1 H2SO4), glucoacidimetric index, cluster weight (g), yield per plant (kg vine -1). Content of sugars was determined by refractometer. Titratable acidity (g L-1 sulphuric acid) was determined by titrating 0.1 N NaOH. Data is analyzed using analysis of variance (Duncan) by SPSS 16.0 for Windows programme. Differences are considered significant a 5% level of probability. The statistical analysis will be performed separately for each parameter. Regarding the results achieved for sugars accumulation at Victoria cultivars the best influence was represented by experimental variant with 22 buds/vine (149 g L-1). In all variants the value of sugars was lower for Coarna Neagra than Victoria cultivar. Total acidity had a higher value for both cultivars under the influence of 30 buds/vine.
