Soil salinization and secondary salinization are important factors limiting watermelon production.In this study,we used selenium-contained watermelon Jincheng No.5 as experimental material to analyze the effects of foliar appli-cation of melatonin on watermelon seedlings under salt stress.The results showed that spraying melatonin on the leaves could effectively alleviate the damage caused by salt stress on watermelon seedlings,promote the growth of watermelon seed-lings,increase the photosynthetic pigment content and antioxidant enzyme activity under salt stress,and decrease the con-tent of malondialdehyde and relative conductivity.Among them,100 μmol/L melatonin had the best effect on relieving salt stress of watermelon seedlings.
