摘要:

【目的】探讨不同种类的植物生长调节剂赤霉酸(GA3)、芸苔素内酯(BR)、噻苯隆(TDZ)在骏枣上的残留消解规律及其对果实黄酮、酚酸类化合物的影响,为科学规范使用植物生长调节剂提供理论依据。【方法】在红枣盛花期以叶面喷雾分别施用18 g/hm2、36 g/hm2 GA3,并与BR(45 mg/hm2)、TDZ(1.8 mg/hm2)同时喷施,采用超高效液相色谱串联质谱测定施药后叶片GA3、TDZ的残留量,基于广泛靶向代谢组学分析果实中黄酮、酚酸含量的变化。【结果】2种剂量的GA3施药后14 d在骏枣上的残留量分别为0.10 mg/kg、0.20 mg/kg;TDZ的残留量为0.01 mg/kg,低于MRL值;GA3、TDZ在骏枣上的消解率均在90%以上。2种剂量GA3的半衰期分别为3.73和4.26 d,TDZ的半衰期为1.63 d。GA3、BR、TDZ处理后,骏枣果实中黄酮类化合物儿茶素没食子酸酯、表儿茶素没食子酸酯、异槲皮苷、芦丁、槲皮素等上调;酚酸类化合物苯甲酸、水杨酸苯酯、咖啡酸苯乙酯、肉桂酸等上调。【结论】 GA3、TDZ在骏枣上降解较快,施用适量的GA3、BR、TDZ有助于提高果实中黄酮、酚酸的含量。

Abstract:

【Objective】 To explore the residual digestion patterns of different plant growth regulators such as gibberellic acid (GA3), brassinolide (BR), and thidiazuron (TDZ) on jujube and their effects on fruit flavonoids and phenolic compounds in the hope of providing a theoretical basis for the scientific and standardized use of some plant growth regulators. 【Methods】 18 g/hm2 and 36 g/hm2 GA3 were applied by foliar spray at the full bloom stage of jujube, and they were sprayed simultaneously with BR (45 mg/hm2) and TDZ (1.8 mg/hm2). Meanwhile, ultra-high performance liquid chromatography tandem mass spectrometry were used to determine the residual levels of GA3 and TDZ in leaves after application, and analyzed the changes in flavonoid and phenolic acid content in fruits based on extensive targeted metabolomics analysis. 【Results】 The residual amounts of GA3 at two kinds of doses on junjube were 0.10 mg/kg and 0.20 mg/kg, respectively, 14 days after application. The residual amount of TDZ was 0.01 mg/kg, which was lower than the MRL value. The digestion rates of GA3 and TDZ on junjube were both above 90%. The half-lives of the two doses of GA3 were 3.73 days and 4.26 days, respectively, while the half-lives of TDZ was 1.63 days. After treatment with GA3, BR, and TDZ, the flavonoid compounds such as catechin gallate, epicatechin gallate, isoquercetin, rutin, and quercetin in junjube fruit were upregulated; Phenolic acid compounds such as benzoic acid, phenyl salicylate, phenylethyl caffeic acid, cinnamic acid were upregulated, too. 【Conclusion】 GA3 and TDZ degrade rapidly on junjube, and the application of appropriate amounts of GA3, BR, and TDZ helps to increase the content of flavonoids and phenolic acids in the fruit.
