Effects of Aspirin on Physiological Characteristics of Muskmelon Seedlings Under Chilling Stress

Taking the muskmelon(cv.Baishami)seeds as the material,which soaked 24 hours with different concentrations of Asp under the room temperature,the effects of Asp on the seedlings' physiological characteristics under the chilling stress were studied.The results showed that the muskmelon seedlings grown from seeds soaking in aqueous solutions(60~2 000 mg/L)of Asp displayed enhanced tolerance to chilling stress,the effect of 150 mg/L Asp was the best,which obviously enhanced the leaf blade antioxidant enzymes activities,and the soluble sugar content;obviously reduced the rate of electrolyte leaching,strengthened the resistance of the melon seedlings to the chilling stress,decreased and alleviated the effects of chilling injury.
