The physiological and biochemical indexes related to chill resistance in the leaves of two different chilling sensitive eggplant cultivars were investigated under 5 ℃ and 8 ℃ low temperatures compared with the normal temperature 25 ℃ (control).The results showed that as the temperature dropped,the permeability of plasma membrane and the content of malondialdehyde (MDA) increased,the activity of superoxide dismutase (SOD) and peroxidase (POD) raised in two cultivars.Catalase (CAT) activities in high chilli...
