Abstract: 【Objective】 To explore the application effect of oxidized glutathione(GSSG)by foliar praying in potato production.【Methods】 In this study,0,450,900,1 350 and 1 800 g/hm2 concentrations of GSSG were set and sprayed at the 20th days after emergency.Then,leaf area index,SPAD value,dry matter accumulation,yield,starch content and reduced sugar content in tuber were determined to clarify the impact of GSSG on potato yield and quality.【Results】 GSSG could promote the increase of potato leaf area index,SPAD value,dry matter accumulation,and potato yield and starch content were increased,but reduced sugar content in tuber was decreased.The suitable application rate of GSSG was 442.50 g/hm2 in potato.【Conclusion】 Foliar spraying oxidized glutathione could increase potato yield and improve the nutritional quality of tuber,which has certain application value in potato production.
