摘要:

【目的】无核化与膨大处理是提高葡萄商品性的重要措施,通过分析不同浓度赤霉素(GA3)和细胞分裂素类似物氯吡脲(CPPU)混合处理下‘阳光玫瑰’葡萄果实品质、香气组分积累的差异,旨在阐明不同无核化与膨大处理配方对葡萄果实品质的影响,从而为实际生产应用提供指导。【方法】以‘阳光玫瑰’葡萄为试验材料,分别在盛花期进行A组(10.0 mg·L-1 GA3+1.0 mg·L-1 CPPU)、B组(25.0 mg·L-1 GA3+1.0 mg·L-1 CPPU)、C组(25.0 mg·L-1 GA3+3.0 mg·L-1 CPPU)、D组(50.0 mg·L-1 GA3+5.0 mg·L-1 CPPU)、X组(15.0 mg·L-1 GA3+3.0 mg·L-1 CPPU)和清水对照(CK)6组无核处理,盛花后15 d在C组处理上进行P0(清水)、P1(15.0 mg·L-1 GA3+3.5 mg·L-1 CPPU)、P2(35.0 mg·L-1 GA3+3.5 mg·L-1 CPPU)、P3(55.0 mg·L-1 GA3+3.5 mg·L-1 CPPU)膨大处理,比较不同无核化和膨大处理配方对葡萄果实外观形态指标,色泽指标和香气组分的影响。【结果】不同无核处理的果实无核率均高于对照,其中D组处理下果实无核率达100%。从果实品质上看,D、C两组处理下果实的粒重最高、横纵径最大、果皮亮度最高和耐贮藏性最强,B、C两组糖类积累量最高、提高固酸比效果最显著;从香气物质上来看,不同无核处理均增加了香气种类。C组处理能提高萜烯类、醛类香气组分含量,增加了香气的层次。花后膨大处理中,P2和P3两组处理显著提高果实质量、增大果实横纵径和提高果实耐贮藏性,P2处理下果皮亮度和饱和度的提高最为显著,P1和P2两组处理则显著提高果实糖类积累,降低酸度;3组处理均降低了香气的浓度,P2处理下更多的香气浓度上升,在膨大果实的同时保留了果实香气多样性。【结论】盛花期施用25.0 mg·L-1 GA3+3.0 mg·L-1 CPPU,花后15 d施用35.0 mg·L-1 GA3+3.5 mg·L-1 CPPU复合处理,可在提高‘阳光玫瑰’葡萄果实无核率和膨大效果的基础上提高果实的综合品质。

Abstract:

【Objective】 Seedless treatments and swelling treatments are important measures to improve the marketability of grapes. This study aimed to determine the effects of different seedless and swelling treatment formulas on grape fruit quality by analyzing the differences in fruit quality and aroma component accumulation under different concentrations of GA3 and CPPU mixture treatments for 'Shine Muscat' grapes, with a view to providing guidance for practical production applications. 【Method】 Taking 'Shine Muscat' grapes as materials, A group (10.0 mg·L-1 GA3+1.0 mg·L-1 CPPU), B group (25.0 mg·L-1 GA3+1.0 mg·L-1 CPPU), C group (25.0 mg·L-1 GA3+3.0 mg·L-1 CPPU), D group (50.0 mg·L-1 GA3+5.0 mg·L-1 CPPU), X group (15.0 mg·L-1 GA3+3.0 mg·L-1 CPPU) and water control (CK) were carried out for seedless treatments in six groups at full-bloom stage, respectively. 15 days after full-bloom, P0 (clear water), P1 (15.0 mg·L-1 GA3+3.5 mg·L-1 CPPU), P2 (35.0 mg·L-1 GA3+3.5 mg·L-1 CPPU), and P3 (55.0 mg·L-1 GA3+3.5 mg·L-1 CPPU) were carried out for swelling treatments in three groups on group C treatment. The effects of different seedless treatment and swelling treatment formulas on the appearance morphological indexes, color indexes and aroma components of grape fruits were compared. 【Result】 The seedless rate of fruits treated with different seedless methods was higher than that of the control group, with the D group treatment achieving a 100% seedless rate. In terms of fruit quality, the D and C groups had the highest grain weight, the largest diameter, the highest skin brightness, and the strongest storability. The B and C groups had the highest sugar accumulation and the most significant increase in the solid-acid ratio. Regarding aromatic substances, different seedless treatments increased the variety of aromas. The C group treatment increased the components of terpenes and aldehydes, adding layers to the aroma. In the post-bloom fruit swelling treatments, groups P2 and P3 significantly improved fruit quality, increased fruit diameter, and enhanced storability. The P2 treatment most notably increased skin brightness and saturation. Group P1 and P2 significantly increased sugar accumulation and reduced acidity. All three treatments reduced the concentration of aromas, with P2 showing a greater increase in aroma concentration, and expanding the fruit while preserving its aromatic diversity. 【Conclusion】 Applying 25.0 mg·L-1 GA3+3.0 mg·L-1 CPPU during the full-bloom stage, with 35.0 mg·L-1 GA3+3.5 mg·L-1 CPPU post-bloom 15 days later, could improve the seedless rate and expansion effect of 'Shine Muscat' grape fruits while enhancing the overall fruit quality.
