In order to study the effect of Putrescine on some quantitative and qualitative traits of barberry in “on” (2018) and “off” (2019) years, an experiment was carried out in a completely randomized block design with factorial arrangement and three replications. Putrescine solution (0, 0.1, and 1 mM/L) sprayed at full bloom and the fruit set stage. Wet and dry fruit weight, length and diameter, pH, anthocyanin and phenol content of berry measured in two years. The results showed that all parameters differed significantly in the “on” and “off” years. The content of acids, anthocyanins, and phenols was higher (9.52, 2.98 and 2.26 percent, respectively) in the “on” year than in the “off” year. In addition, Putrescine at a concentration of 1 mM /L was the most effective treatment for increasing all parameters except acidity and phenolic content. In addition, this treatment increased pH, soluble solids content, length, and fresh and dry weight (21.59, 9.45, 12.47 and 23.58 percent, respectively) of berries in the “on” year. There was no significant difference between measured parameters in the “on” and “off” years. Putrescine treatment (1 mM /L) reduced some quantitative and qualitative traits in on year.
