摘要:

【目的】 研究油菜素内酯(brassinolide,BR)处理对甜瓜中啶虫脒、多菌灵、苯醚甲环唑、腈菌唑的降解作用及其机理。【方法】 以甜瓜为材料,喷施油菜素内酯和清水2种处理后,喷施农药,在2 h(0 d),1、3、5、7、9、15和24 d分别取样,测定甜瓜果实中农药残留含量、解毒酶活性、活性氧含量、解毒基因表达量以及代谢产物的变化。【结果】 与清水对照组相比,油菜素内酯处理组显著(P<0.05)降低了甜瓜果实中啶虫脒、多菌灵、苯醚甲环唑、腈菌唑的含量,减少丙二醛(malonaldehyde,MDA)生成量,显著降低了超氧阴离子(O2-)产生速率,保持较高解毒酶过氧化氢酶(catalase,CAT)、过氧化物酶(peroxidase,POD)、苯丙氨酸解氨酶(L-phenylalaninammonia-lyase,PAL)、谷胱甘肽还原酶(glutathionereductase,GR)活性,且使可溶性蛋白、还原型谷胱甘肽(Glutathione,GSH)、过氧化氢(Hydrogenperoxide,H2O2)含量保持在较高的水平。对超氧化物歧化酶(superoxidedismutase,SOD)、抗坏血酸过氧化物酶(ascorbateacid,APX)无显著影响。6种解毒基因的表达量在一定程度上有所增加。【结论】 喷施油菜素内酯能提高甜瓜果实中解毒物质的含量、解毒酶的活性、解毒基因的表达量以及缓解活性氧代谢所产生的危害,使甜瓜果实中的农药残留含量降低。

Abstract:

【Objective】 To explore the degradation of acetamiprid, carbendazim, difenoconazole and nitriconazole in muskmelon treated with Brassinolide (BR) and its mechanism.【Methods】 Melons were treated with Brassinolide and clean water, and then sprayed with pesticides.Samples were taken at 2 h, 1 d, 3 d, 5 d, 7d, 9 d, 15 d and 24 d respectively to determine the content of pesticide residues, detoxifying enzyme activity, reactive oxygen species content, detoxifying gene expression and metabolites in the muskmelon fruit.【Results】 Compared with the water control group, the brassinolide treatment group significantly (P<0.05) reduced the contents of acetamiprid, carbendazim, difenoconazole and nitriconazole in melon fruit, reduced the production of malonaldehyde (MDA), significantly reduced the production rate of superoxide anion (O2-), and maintained a high detoxification enzyme catalase (CAT), peroxidase (POD) Phenylalanine ammonia lyase (PAL) and glutathione reductase (GR) activities, and the contents of soluble protein, reduced glutathione (GSH) and hydrogen peroxide (H2O2) were maintained at a high level.It had no significant effect on superoxide dismutase (SOD) and ascorbate peroxidase (APX).The expression of six detoxification genes increased to some extent.【Conclusion】 Spraying brassinolide can increase the content of detoxifying substances, the activity of detoxifying enzymes, the expression of detoxifying genes and alleviate the harm caused by reactive oxygen metabolism in melon fruit, and finally reduce the content of pesticide residues in melon fruit.

Key words: muskmelon; pesticide residues; brassinolide; detoxification enzymes and genes; detoxifying substances; active oxygen metabolism
