Research Concerning the Correlation between Crop Load, Leaf Area and Grape Yield in Few Grapevine Varieties

Yield and physicochemical characteristics of ‘BRS Magna’ and ‘Isabel Precoce’ grapes influenced by pruning in the São Francisco river valley

“…The amount of buds kept after pruning influences the carbohydrate stocks in the plant (PELLEGRINO et al, 2014), and can affect grape yield and quality. However, the responses vary depending on the grape cultivar (DOBREI et al, 2016;CHOUGULE et al, 2008;BENISMAIL et al, 2007;SOMKUWAR e RAMTEKE, 2006).…”

The Rate of Water Loss in Relation to Internodes Position and Wood Maturity in Vine Chords

“…Samples were taken from the vine experimental plots of BUSAMV Timisoara. The canes were analyzed over the entire length (19 internodes; IN [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] ), from each internode being extracted samples, which have been subjected to drying under controlled conditions. The rate of water loss, and associated parameters, was made with a infrared thermobalance (AXIS, ATS 60 Model), with an accuracy of ± 0.001g.…”

“…Wood maturation in canes, and consequently resistance to wintering and frost, and the viability of buds, has been associated with the specificity of biological material, being well known, varieties and local populations with of woodcanes ripening and high frost resistance, compared to others more sensitive, in similar vegetation conditions (Dobrei et al, 2015). Sugar content was the most frequently studied in grapes and other horticultural species, according to carbohydrate metabolism in plants (Wu et al, 2011), the relation of vine with soil, clime and technological factors (Jivan and Sala, 2014), production quality and wine processes (Dobrei et al, 2010(Dobrei et al, , 2016Blidariu et al, 2013), but equally important is the sugar content of the canes for the maturation of wood, winter hardiness, viability of buds and quality of chords for reproductive biological material (Rogiers et al, 2010;Smith et al, 2010).…”

“…The biological material was represented by grape cultivar Burgund mare, to which were analyzed individually all internodes distributed on the chord length (internodes number IN [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] ). The rate of water loss and associated parameters (maximum rate of water loss -RWL Max , total drying time -T, time to achieve RWL Max -t RWLMax ) were determined from the Burgund mare vine cultivar, in controlled condition.…”

Cane Pruning Intensity of Vine as a Substantial Factor Influencing Physico-Chemical Attributes of Berries Cultivar ‘Regent’

“…Various sensitivity to the pruning level probably depends mainly on different phenotypic behaviour (Baiano and Terracone 2012). Thus, although pruning is a technological stage extensively studied, it can be optimised for each variety according to the production destination, environmental conditions and vineyard management (Dobrei et. al 2016).…”
