Abstract:

With the grape cultivar ‘Zaoxia Meigui’ as the test material,used first and second spraying different GA₃ and CPPU concentrations,the effect of different GA₃ and CPPU concentrations on grape seedless rate and fruit quality were studied.The results showed that,treatment of GA₃ and CPPU could increase seedless rate of ‘Zaoxia Meigui’.Treatment at 3 days before blooming was better than that at full blooming.Treatment Ⅳ (applying GA₃ 50 mg/L 3 days before blooming+GA₃ 30 mg/L and CPPU 5 mg/L 2 weeks after blooming) resulted in the highest seedless rate of 100%.Second applying could improved single berry weight,vertical and horizontal diameter and soluble solid content.Treatment Ⅲ (applying GA₃ 30 mg/L 3 days before blooming+GA₃ 30 mg/L and CPPU 5 mg/L 2 weeks after blooming) led to the best single berry weight and vertical and horizontal diameter,while treatment Ⅱ (applying GA₃ 10 mg/L 3 days before blooming+GA₃ 30 mg/L and CPPU 5 mg/L 2 weeks after blooming) generated the highest soluble solid content.Overall consigeration,treatment Ⅲ was the best treatment,which generated a seedless rate of 96.67%,a single berry weight of 7.66 g and a soluble solid content of 16.4%.
