Calla Lily (Zantedeschia sp.) is a day-neutral plant of Araceae family that is native to South and Central Africa. The number and quality of this flower can be influenced by plant growth regulators such as gibberellic acid. For this purpose, research was conducted to evaluate the effect of gibberellic acid (GA3) (0, 500, and 600 mg/L) on the quantitative and qualitative characteristics of two varieties of Calla lily. This experiment was conducted as a factorial in randomized complete blocks design in three replications in the greenhouse of the Faculty of Agriculture, Shahid Chamran University of Ahvaz. The results demonstrated that the application of gibberellic acid (especially at a concentration of 600 mg/L), significantly increased leaf fresh and dry weight, flower fresh and dry weight, leaf area, number of buds, spath length, vase life, amount of chlorophyll and carotenoid of leaf and spath, carbohydrate and starch in both Z. aethiopica and Z. rehmanii species. This increase was more in aethiopica than rehmanii species and reached the highest level in most characteristics such as leaf dry weight, fresh weight of flowers, number of buds, cut flowers length, vase life, leaf chlorophyll and carotenoids, and spot chlorophyll. In general, the results showed that the use of GA3 can improve Calla Lily's quantitative and qualitative characteristics.
