摘　　要：为了探明喷施槲皮素对板栗生长及坚果品质的影响,为槲皮素在板栗生产中的应用提供科学依据。以6年生燕山早丰板栗嫁接树为试材,以不同浓度(0、150、300、600、1 200μmol/L)槲皮素进行叶面喷施,单株喷施500 mL,探讨对板栗叶片抗性指标、结果枝生长、产量及品质的影响。结果表明:喷施1 200μmol/L槲皮素可显著提高板栗叶片APX活性、CAT活性、可溶性糖含量、蛋白质含量,分别较对照提高了141.2%、75.3%、40.0%、93.6%;喷施槲皮素可降低板栗空苞率,但对板栗枝条生长和产量影响不显著;喷施槲皮素主要提高了坚果可溶性糖含量与淀粉含量,喷施1 200μmol/L槲皮素可溶性糖含量最高,较对照提升30.2%,喷施600μmol/L槲皮素淀粉含量最高,较对照提升20.7%。通过主成分分析及隶属函数综合评价得出,喷施1 200μmol/L槲皮素为最优处理。In order to investigate the effects of quercetin spraying on the growth and nut quality of Chinese chestnut,and to provide a scientific basis for the application of quercetin in Chinese chestnut production.The grafted 6-year-old‘Yanshanzaofeng’Chinese chestnut tree was used as the test material,and quercetin was sprayed at different concentrations(0μmol/L,150μmol/L,300μmol/L,600μmol/L,1200μmol/L)in foliar spraying,with 500 mL of quercetin in a single plant,to investigate the effects on the resistance indexes of Chinese chestnut leaves,fruiting branch growth,yield and quality.The results showed that spraying 1200μmol/L quercetin significantly increased APX activity,CAT activity,soluble sugar content and protein content of Chinese chestnut leaves by 141.2%,75.3%,40.0%and 93.6%,respectively,compared with the control.Spraying quercetin could significantly reduce the rate of empty bracts of Chinese chestnut,but had no significant effect on the growth and yield of Chinese chestnut branches;quercetin mainly improved the soluble sugar and starch content of nuts,and the spraying of 1200μmol/L had the highest content of soluble sugar,which was 30.2%higher than that of the control,and the spraying of 600μmol/L had the highest content of starch,which was 20.7%higher than that of the control.Through principal component analysis and affiliation function,it was concluded that spraying 1200μmol/L quercetin spraying was the optimal treatment.
