Open publisher page 0 citations

Abstract

'Fengxiang'strawberry was used as test material,the effects of low concentration of H2O2on physiological character related to chilling resistance of strawberry seedlings under low temperature stress was studied.The results showed that H2O2 could inhibit the membrane permeability,decrease the malondialdehyde(MDA) content,improve the activities of superoxide dismutase(SOD),catalase(CAT),peroxidase(POD),ascorbic acid peroxidase(APX),glutathione reductase(GR) and dehydroascorbic acid reductase(DHAR) in strawberry seedling cells.
