Yields not affected byearly leaf removal

摘要

Early leaf removal in whitegrapes has several benefits. In eastern Washington State, leaf removal in wine grapes is typically done between fruit set and bunch closure to open up the canopy, reduce disease pres- sure, and improve fruit quality. But is that the best time?Washington State University researchers studied fruit zone leaf removal in eastern Washington the last two years, looking at the effects on vine development and fruit quality in white wine grapes. This year, they are expanding the research to red varieties and will study how leaf removal influences wine quality.
