چکیده انگلیسی

Several red grapevine varieties like Feteasca neagra, Cabernet Sauvignon, Pinot noir, Merlot, Burgund and Cadarca were investigated during 2014-2015 in the vineyard Minis-Maderat. Following research, correlations and mathematical models were made differentiated between crop load, leaf area and grapes quality (sugar content, titratable acidity, sugar-acidity index and anthocyanins). Optimal crop load varies from one variety to another, depending on each of them. The effect of four crop load (20, 30, 40 and 50 buds/vine) was study for their influence on yield and grape quality. The quality of production is an indicator that can be best optimized by proper pruning. From this point of view, Feteasca neagra and Merlot varieties had the best behaviour, while the Burgund and Cadarca recorded smaller qualitative differences between experimental variants. Correlations and mathematical methods vary from one variety to another; superior quality indices were recorded at different crop load, determined with precision by statistical and mathematical methods and interpretation. Although pruning is a technological stage extensively studied, it can be optimized for each variety according to the production destination, environmental conditions and vineyard management. Statistical analysis showed that the Cabernet Sauvignon variety perform the best concerning the grape quality parameters while Burgund and Merlot are varieties with week results in both experimental years. The aim of the study was to investigate the influence of crop load on grape quality, grape yield and photosynthetic efficiency.
