Defoliation of two-wire vertical trellis: effect on grape quality

2017

ABSTRACTBasal leaves were removed from Cabernet Sauvignon vines trained to a two-wire vertical trellis at fruit set and at veraison. Leaf removal did not modify total soluble solids and titratable acidity at harvest. Defoliation at fruit set of lower cordon recovered the grape anthocyanin composition gap between upper and lower cordons and that produced a positive effect on anthocyanin synthesis. Hence, control of the upper cordon and defoliation of fruit set of the lower cordon treatments showed comparable values of anthocyanins. Defoliation at veraison did not produce any appreciable effect. This study shows that skin anthocyanin composition in a two-wire vertical trellis can be modified …

DETERMINATION OF THE OPTIMAL MOMENT OF HARVESTING FOR CABERNET SAUVIGNON AND MERLOT GRAPES IN DRĂGĂŞANI VINEYARD

2011

This paper presents an analysis of the main characteristics of black grapes during ripening and determining the optimum moment to harvest the grapes in the vineyard Drăgăşani. Monitoring process of maturation of the grapes has been done on the varieties of grapes for red wines Cabernet Sauvignon and Merlot from Drăgăşani vineyard.

Vegetative and Reproductive Behaviour of Vitis vinifera L. (cv. ‘Cabernet Sauvignon’) Vines Growing Under Non-Irrigated Conditions and Moderate Water…

2007

An experiment was carried out to evaluate the effect of different levels of water stress and different irrigation systems to the vegetative and reproductive behaviour of Cabernet Sauvignon ines/140Ru, vertically trained, during the growing season 2003-2004. The vineyard was located in Sicily (in the south of Italy); the soil was loamy-sand and the climate semi-arid. Were compared five treatments: four treatments irrigated, maintaining a moderate water stress level, by drip irrigation (T1) and sub-irrigation (T2, T3 and T4) and one treatment non-irrigated (T5). The sub-irrigation treatments were different by the number and the distance of the water tubes by the rows of vines. The results sho…

Distribution of YLOID in soil-grapevine system (Vitis vinifera L.) as tool for geographical characterization of agro-food products. A two years case …

2017

The knowledge of a chemistry relationship between the soil and the agricultural products is an important tool for the quality assessment of food. We studied YLOID (Y, La and lanthanoids), recognized as very useful tracers due their coherent and predictable behavior, to trace and evaluate their distribution from soil to the grape in Vitis vinifera L. Because much of the world’s viticulture is based on grafting, and rootstocks have proved affect vine growth, yield, fruit and wine quality, we carried out experimental trials to analyse the YLOID distribution of two different red cultivars, grafted onto six different rootstocks, on the same soil. The YLOID amounts, the relationship Heavy vs Ligh…

THE EVOLUTION OF COMPOUNDS IN THE AGING PROCESS OF THE DRĂGĂŞANI CABERNET SAUVIGNON WINES

2011

This paper presents the influence of raw material on wine aging and determining of the optimal duration of wine aging in oak vessels and glass vessels. The potential quality of red wines from Cabernet Sauvignon Drăgăşani is highlighted more in the aging process to oak vessels and glass vessels.
