Abstract

Ethephon enhanced color development in 9Tokay9 and 9Emperor9 table grapes. The most effective concentrations were 200 ppm for 9Tokay9 and 100 to 200 ppm for 9Emperor.9 Berry firmness was reduced. The most effective time of application in one of two 9Tokay9 vineyards was shortly after color development began. Application when 10 to 80% of the berries showed color was equally effective with 9Emperor.9
