Tree peony (Paeonia suffruticosa Andr.), which is a traditional flower cultivated in China, rapidly becoming an important species the cut industry. Thus, extending vase life of tree flowers major goal Melatonin, new type antioxidant, plays regulatory role preservation flowers. Therefore, this study employed “Diguan” as test material to investigate preservative effects antioxidant melatonin on “Diguan”. We examined terms their morphology, lifespan, relative fresh weight, diameter, and water balance value after treatments with different concentrations (0.2, 0.3, 0.4, 0.5 mg·L−1) select optimal treatment concentration. Considered together, these analyses clarified Specifically, exogenous application positively affected by improving increasing soluble protein content enzyme activities, thereby prolonging ornamental period The weight branches significantly correlated protein, lifespan increases values branches, large correlation coefficient. It can be used indicator measure subsequent research. 0.4 mg L−1 was for preserving because its positive duration quality.
