摘要
为促进优良葡萄品种在生产中的应用推广,本研究以日光温室栽培5年生无核翠宝为试材,设置植物生长调节剂保果(T1处理:盛花后2 d,10 mg·L^(-1) GA_(3)+0.5 mg·L^(-1) CPPU)和膨果(T2处理:花后15 d,15 mg·L^(-1) GA_(3)+0.5 mg·L^(-1) CPPU)2个处理,以常规栽培为对照,于果实成熟期对外观、品质及感官指标进行测定和分析。结果表明,与对照相比,单独采用保果和膨果处理均能提高粒重、穗重,改善外观品质,但同时也会导致可溶性固形物含量和固酸比降低,果皮涩度和果皮咀嚼粗糙感显著提升。综合分析表明,单独采用保果处理的综合品质最佳,该处理下可溶性固形物和总酸含量分别为21.20%和0.54%;穗重和粒重分别达到553.97和5.02 g,较对照提高88.08%和28.72%。在新疆产区日光温室栽培条件下,盛花后2 d使用10 mg·L^(-1) GA_(3)+0.5 mg·L^(-1) CPPU进行保果处理能够有效改善果穗外观品质,同时对内在品质和口感影响较小,适合在生产中应用。本研究结论为无核翠宝的栽培管理提供了技术参考。
To promote the application and extension of excellent grape varieties in production,this study used five-year-old Wuhe Cuibao grapes grown in a greenhouse as experiment variety.Plant growth regulators were applied in combination during the fruit retention stage(T1 treatment:2 days after full bloom,10 mg·L^(-1) GA_(3)+0.5 mg·L^(-1) CPPU)and the fruit enlargement stage(T2 treatment:15 days after bloom,15 mg·L^(-1) GA_(3)+0.5 mg·L^(-1) CPPU).A conventional cultivation method was used as the control.The appearance,quality,and sensory indicators of the fruit were measured and analyzed at fruit maturity.The results showed that both the fruit retention and fruit enlargement treatments increased berry and cluster weight,and improved appearance quality.However,these treatments also led to a decrease in soluble solids content and the soluble solids/acid ratio,with a significant increase in skin roughness and astringency.Comprehensive analysis indicated that the fruit retention treatment alone achieved the best overall quality.Under this treatment,the soluble solids content and total acid content were 21.20%and 0.54%,respectively,while the cluster and berry weights reached 553.97 g and 5.02 g,representing increases of 88.08%and 28.72%,respectively,compared to the control.Under the greenhouse cultivation in the Xinjiang production area,applying 10 mg·L^(-1) GA_(3)+0.5 mg·L^(-1) CPPU for fruit retention 2 days after full bloom has effectively improved the appearance quality of grape clusters while having had minimal impact on internal quality and taste,thus making it suitable for production applications.The conclusions of this study provide technical references for the cultivation management of Wuhe Cuibao grapes.
