Most seedless table grapes are treated with gibberellic acid (GA 3 ) to increase berry size and uniformity ( Diaz and Maldonado, 1992 ; Dokoozlian et al., 1994 ; Reynolds et al., 1992 ; Wolf et al., 1994 ). Application of the synthetic

over time) was not given. Gibberellic acid (GA) is used to help break seed dormancy of many angiosperms ( Taiz and Zeiger, 2002 ). For instance, at 4 weeks after treatment with 900 ppm GA 3 , Dweikat and Lyrene (1989) found 50% of V. corymbosum

. Another approach to increase the yield of a machine-harvested leafy greens crop is to use gibberellic acid (GA) to increase crop height at harvest. Gonzalez and Marx (1983) found that, for spinach ( Spinacia oleracea L.) sown in late summer or fall, 20

During the last decade, a novel irrigation strategy, partial root zone drying (PRD), has been developed for grape ( Vitis vinifera ) production ( Dry and Loveys, 1999 ). The PRD irrigation technique was designed to trigger the abscisic acid (ABA
