This research was conducted in order to investigate the effect of hydrogen peroxide and brassinosteroid hormone on growth after harvesting Kino mandarin based on a completely randomized design with 5 treatments and 3 replications on Kino mandarin fruit harvested from Jiroft Commercial Gardens located in Jiroft Agriculture and Industry. Test treatments were by immersion method (for 5 minutes) and included oxygenated water with concentrations of 10 and 15 µM; brassinosteroid with concentrations of 0.5 and 1 mg/l; and distilled water treatment (control). Then the fruits were transferred to the cold room and kept at 4 degrees Celsius for 30 days and every 10 days the amount of damaged fruits, acidity and titratable acid, amount of soluble solids, lipid peroxidation, amount of peroxide hydrogen, peroxidase enzyme activity and catalase enzyme activity were investigated. The results showed that the effect of both treatments on improving the post-harvest life and quality characteristics of tangerine fruits was significant compared to the control. Thus, the use of brassinosteroid and hydrogen peroxide caused a decrease in the percentage of damaged fruits, lipid peroxidation, the amount of hydrogen peroxide, and increased activity of peroxidase enzyme and catalase enzyme activity during storage, and brassinosteroid hormone with a concentration of 1 mg/l and then hydrogen peroxide (15 µM) compared to other treatments had the greatest effect during storage on improving the life after harvesting of Kino mandarin fruit.
