USE OF GIBBERELLIN A5 TO INCREASE THE YIELD AND QUALITY OF GRAPES

摘要

A method for increasing the harvest yield of wine grapes per hectare, via increased berry numbers per bunch, while enhancing grape quality. The method comprises applications of a solution comprising one of gibberellins GA5, GA4, or a mixture of GA4 and GA7 (GA4/7) to developing grape berry bunches, at a concentration selected from the range of about 5 mg/L to about 50 mg/L. The solution is preferably applied during a time selected from the range of about 60 days to about 30 days before veraison.
