- 摘要:
- 以4年生“阳光玫瑰”葡萄为试材,于盛花期和花后2周分别使用赤霉素(GA3)和氯吡脲(CPPU)处理,探究不同浓度GA3和CPPU对“阳光玫瑰”葡萄果实无核化及品质的影响。结果表明:各浓度的激素处理均不同程度改善了“阳光玫瑰”葡萄的果实品质,其中在盛花期和花后2周均使用低浓度的GA3与CPPU混合溶液可明显提高果实的无核率,增大果实横径、单果质量及果实硬度,提高可溶性固形物含量,降低可滴定酸含量,促进果实成熟,改善果实风味,以盛花期及花后2周均用25 mg`L-1 GA3+5 mg`L-1CPPU(处理D)浸蘸“阳光玫瑰”葡萄花/果穗综合表现最佳,能有效提高果实商品性,增加经济效益,该结果可为生产者提供技术支持和参考依据。
- Abstract:
- Four-year-old ‘Shine Muscat’ grapevine was selected as test material,and the effects of different concentrations of gibberellin(GA3)supplemented with N-(2-chloro-4-pyridyl)-N′-phenylurea(CPPU)treatments at different stages on seedlessness and fruit quality of ‘Shine Muscat’ grapevine were investigated in peak florescence and 2 weeks after blossoming.The results showed that,co-treatment with lower concentrations of GA3 and CPPU could significantly improve the fruit seedless rate,transverse diameter,berry weight and fruit firmness.Meanwhile,the total soluble solids increased,but the total acid content showed the trend of reducing.By applying co-treatment with lower concentrations of GA3 and CPPU promoted the fruit mature and improved fruit flavor.Comprehensive consideration for the seedless rate and fruit quality of the ‘Shine Muscat’ grapevine,the best co-treatment in production was to apply with 25 mg`L-1 GA3+5 mg`L-1 CPPU in peak florescence,and 25 mg`L-1 GA3+5 mg`L-1 CPPU at 2 weeks after blossoming (Treatment D).The treatment could effectively improve the fruit commodity and increase economic benefits.The results of the research would provide technical support on solving the key problems during cultivation of the new grapevine cultivar ‘Shine Muscat’.
