Foliar melatonin applications are crucial for grape quality as they can enhance skin color development, increase antioxidant capacity and nutritional value of grapes. The effectiveness of preharvest melatonin applications may change depending on fruit species, variety, application time, and dose. In the current study, it was utilized from various doses of melatonin application, including 0, 0.25, 0.50, and 1 mmol l-1 for improving the phytochemical attributes of Crimson Seedless table grape variety. The results of the principal component analysis showed that different doses of foliar melatonin application had different effects on the yield and biochemical attributes of grape variety. But particularly, 1 mmol l-1 and 0.50 mmol l-1 of melatonin doses had significant effects on total phenolic compounds content and antioxidant capacity from the phytochemical properties of Crimson Seedless table grape variety.
