Aim: A study on Sauvignon blanc (SB) cultivar in France showed that curettage had an effect the resilience of GTD grapevines. No experiments, however, have been conducted its effects wine quality, particularly white wines.Methods and results: Grapevines from expressed Esca-foliar symptoms were used for study, with some them having curetted 2014. Subsequently, bunches Control (asymptomatic), Cur...

Yields on 'Concord' grape (Vitis labrusca L.) increased as pruning severity was decreased until the 6th and last year of this study, at which time the yields tended to equalize between the 30 + 10, 50 + 10, and 70 + 10 pruning treatments. By the last year, vines pruned to the 70 + 10 level produced fruit of unacceptable quality. When the 3-node spurs were shoot-positioned, their productivity wa...

Grafting cold-hardy hybrid grapevines may influence their attributes under different pedoclimatic conditions and also contribute to cold-hardiness, plant physiology, affect yield fruit composition. In a six-year study, we evaluated bud survival, development, nutrient deficiencies, yield, composition for three grape varieties: Frontenac, Frontenac blanc, Marquette. The varieties were grafted on ...

The effects of three levels of organic matter removal (OMR) and three levels of soil compaction (SC) on the development of understory vegetation in a central hardwood forest were evaluated 9 years after treatments were applied as part of a national program of long-term soil productivity research. The three levels of biomass removal (OMR) were removal of merchantable boles only (OM0), removal of...

After mechanical harvesting of 'Concord' grapes was totally implemented, the most time-consuming vineyard operation in Arkansas became pruning. Grape producers complain of decreasing availability of qualified labor for pruning and tieing, and feel that pruning should be the next operation mechanized. Single and double curtain vines were established in a 14-year-old vineyard at the Main Station,...
