Effects of low-temperature plasma composite treatment on kiwifruit fruit quality and pesticide residue reduction
摘要
Abstract
To investigate the improving effects of a 300-fold diluted low-temperature plasma composite on fruit quality of three kiwifruit varieties(Hongyang,Donghong,and Ruiyu),and its mitigating effects on pesticide residues in Donghong and Ruiyu kiwifruit,the composite was applied through foliar spraying and root irrigation.The fruit quality was assessed by meas-uring average single fruit weight,hue angle,peel firmness,dry matter content,and soluble solids content.Additionally,common pesticides in kiwifruit were detected to evaluate the reduction effect of low-temperature plasma composite on pesticide residues.The results showed that the application of low-temperature plasma composite had no significant effect on the fruit quality of Hongyang kiwifruit,but in Donghong kiwifruit,it induced an 8.7％decrease in hue angle,a 12.3％reduction in peel firmness,and a 4.2％increase in soluble solids content.After treatment,Ruiyu kiwifruit increased in single fruit weight and soluble sol-ids content by 19.7％and 53.3％respectively,while peel firmness decreased by 15.7％.The surface pesticide concentrations of Donghong kiwifruit treated with low-temperature plasma composite decreased by 43.6％,24.0％,41.7％,and 18.0％for pyrazophos-ethyl,cymoxanil,tebuconazole,and difenoconazole,respectively,compared to the control.In contrast,no residues were detected on Ruiyu kiwifruit.A 300-fold dilution of low-temperature plasma composite significantly enhanced the fruit quality of Donghong and Ruiyu kiwifruits,and effectively reduced the amount of pesticide residues on the fruit surface.关键词
