| Popis: | Climate change, including more volatile weather and longer growing seasons, is causing stress on grapevines (Vitis spp.). A change in harvest timing of wine grapes can have significant consequences. Thus, two methods (crop forcing and complete removal of green tissue) were employed to simulate abiotic vine injury. The harvest of bunch grapes in Mississippi occurs during July, a very hot month. &lsquo Miss Blanc&rsquo and &lsquo Villard Blanc&rsquo had four different crop forcing treatments imposed to determine yield amount and harvest timing. All treatments reduced yield. Harvest was delayed by 50 days, a potentially positive shift that was not enough to escape high temperatures. &lsquo had no flower or fruit development after crop forcing treatments in May and June. &lsquo yields were also significantly reduced by these treatments. Removal of green tissue to simulate injury from weather events such as frost, freeze, wind, or hail in both Mississippi and Oklahoma revealed that lost growth could reduce yields from 19% to 81%, which could influence grape grower management decisions. |
