Abstract:: ‘Kyoho’ grape was used as material for studying the effect of foliar spray of natural mineral fertilizer at growth stage on fruit quality and activities of antioxidant enzymes.The results showed that foliar spray of natural mineral fertilizer was effective on improving the fruit quality of ‘Kyoho’.Fruit firmness，redness and soluble solid content were higher than those of control fruits，with the increase of 6.1%，30.2%，7.0%，respectively.Individual fruit weight and leaf chlorophyll content were not significantly affected by natural mineral fertilizer treatment.The enhanced activities of G-POD and APX in leaves of ‘Kyoho’ were also observed in natural mineral fertilizer treatment.In a word，foliar spray of natural mineral fertilizer at growth stage was helpful for improving ‘Kyoho’ fruit quality，which could be applied for commercial production of table grapes.
