Abstract：In order to study the effects of ozone water treatment on physiological characteristics of ginger seedlings,the seedlings from Gaomi Wulong River farm in Shandong Province were used as the experimental materials,and two treatments were set,which were soil irrigation treatment with ozone water at 1.0 mg/L and leaf spraying treatment with ozone water at 0.6 mg/L.Then the SOD,POD,CAT activity,membrane permea-bility,SPAD value and nitrogen content in ginger seedlings were determined.The results showed that the irri-gation and spraying of ozone water treatments could both significantly increase the antioxidant enzyme activity in leaves,significantly decrease the leaf membrane permeability and obviously improve the stress resistance of ginger seedlings;they also could significantly increase the leaf SPAD value and nitrogen content,and obvious-ly improve the leaf photosynthetic capability of ginger seedlings.The effects of the leaf spraying treatment were better.
