Abstract
[Objective] The aim was to screen exogenous hormone species and effective concentration for improving cold resistance of watermelon seedlings.[Method] With watermelon seedlings as materials,dealing with different foreign substances seedlings,the main growth indicators,chilling injury index and the activity of protective enzymes were determined,and cold hardiness of each treatment was evaluated.[Result] ABA,BA and penicillin can improve the cold tolerance of watermelon seedlings,25 mg/L ABA treatment as the best,50 mg/L ABA treatment followed;1 000 mg/L penicillin and 25 mg/L BA also have some effect;while ethephon reduced the cold tolerance of watermelon seedlings.[Conclusion] Treatment with ABA can promote the growth of watermelon seedlings,at the same time can improve protective enzymes activity of watermelon seedlings,which could be used as an effective means of improving seedling cold tolerance.
