摘要:

为探究不同浓度γ-氨基丁酸(GABA)对樱桃番茄营养品质和抗氧化活性的影响,以樱桃番茄为试材,于第3穗花后15 d开始叶面喷施不同浓度GABA(0,5,10,20,40 mmol/L,分别记为:CK、G5、G10、G20和G40)溶液,探究施用γ-氨基丁酸对樱桃番茄营养品质、内源GABA及抗氧化活性等指标的影响。结果表明:外源GABA处理可以显著提高樱桃番茄营养品质和抗氧化能力。随着处理浓度升高,可溶性糖、总酚、总黄酮含量和糖酸比不断增大,维生素C、可溶性糖、糖酸比等营养品质指标均在G40处理下达到最大值;G40处理下的总酚含量和总黄酮含量显著高于除G20外的其他处理,较CK分别提高了24.26%,91.75%;G40处理下樱桃番茄的番茄红素含量最高,较CK显著提高了85.96%。内源GABA含量随处理浓度升高呈先升高后降低趋势,在G20处理达到最大值,较对照显著提高了101.85%,但G20处理与G40处理无显著差异;DPPH自由基清除活性与FRAP抗氧化能力同步增强,均在G40处理达到最大值,显著高于CK。经相关性分析,可以得出樱桃番茄抗氧化能力与总酚含量、总黄酮含量、番茄红素均呈极显著正相关关系。综上可得,外源GABA(G40处理)可作为一种绿色高效手段提升樱桃番茄果实营养品质及抗氧化活性。

Abstract:

In order to investigate the effects of different concentrations of γ-aminobutyric acid(GABA)on the nutritional quality and antioxidant activity of cherry tomatoes,cherry tomatoes were used as experimental materials.Foliar spraying of GABA solutions with different concentrations(0,5,10,20,and 40 mmol/L,denoted as CK,G5,G10,G20,and G40,respectively)was initiated at 15 days after the anthesis of the 3rd inflorescence.It aimed to explore the impacts of exogenous GABA application on the nutritional quality,endogenous GABA content,and antioxidant activity-related indicators of cherry tomatoes.The results showed that exogenous GABA treatment could significantly improve the nutritional quality and antioxidant capacity of cherry tomatoes.With the increase in treatment concentration,the contents of soluble sugar,total phenols,and total flavonoids,as well as the sugar-acid ratio,increased continuously.Nutritional quality indicators such as vitamin C content,soluble sugar content,and sugar-acid ratio all reached their maximum values under the G40 treatment.The contents of total phenols and total flavonoids in the G40 treatment were significantly higher than those in other treatments except G20,increasing by 24.26% and 91.75% compared with CK,respectively.The lycopene content of cherry tomatoes under the G40 treatment was the highest,which was significantly 85.96% higher than that of CK.The endogenous GABA content first increased and then decreased with the elevation of treatment concentration,reaching the maximum value under the G20 treatment,which was significantly 101.85% higher than that of the control.However,there was no significant difference in endogenous GABA content between the G20 and G40 treatments.Both DPPH free radical scavenging activity and FRAP antioxidant capacity were synchronously enhanced,and both reached their maximum values under the G40 treatment,which were significantly higher than those of CK.Correlation analysis indicated that the antioxidant capacity of cherry tomatoes was extremely significantly positively correlated with total phenols,total flavonoids,and lycopene.In conclusion,exogenous GABA(G40 treatment)can serve as a green and efficient strategy to enhance the nutritional quality and antioxidant activity of cherry tomato fruits.
