In order to evaluate the effect of γ-aminobutyric acid and spermine on some morphological and physiological traits of Damask rose plant, a completely randomized design was carried out in spring and summer 2017 and in Zanjan University in three replications. Experimental treatments consisted of three levels of gamma aminobutyric acid (1, 5, 10 mM) and three levels of spermine (0.5, 1, 1.5 mM). The evaluated traits included morphological traits (plant height, number of flowers, number of flowering branches, plant shadow diameter, average number of flowers per branch and petal dry weight) and physiological traits (total chlorophyll, chlorophyll a, chlorophyll b, carotenoids, leaf flavonoids, petal flavonoids and peroxidase enzyme activity). The results showed that there was a significant difference in all the traits, except plant height, plant shadow diameter and number of flowering branches, compared to the control. Based on the results the concentration of 5 mM gamma aminobutyric acid and 1 mM spermine improved the morphophysiological traits in reproductive stage.
