| ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and east/west face), at veraison, and a group without defoliation, were compared in order to observe the impacts of this management on the productivity, grape and base wine quality. Yield, grape components, must and base wine composition were analyzed for two years. East/west defoliation increased alcohol content and decreased acidity in base wines, while the group without defoliation increased acidity,... |

| Gray mold (GM) caused by Botrytis cinerea is a major disease of grapes (Vitis vinifera) that substantially reduces the yield and quality of grape production in temperate and humid regions of the world. B. cinerea is a necrotrophic fungus that attacks the non-lignified aerial organs of grapes; in particular, berries are highly susceptible during ripening. The polycyclic nature and exponential progress exhibited by GM at the beginning of the its epidemic, as well as the abundant inoculum production, the high dissemination efficiency, the wide host range and the high genetic variability of B. cinerea, explain the difficulties encountered in attempting to control GM. At present, integrated disease management, including cultural and chemical control, is the... |
