Abstract. This study was conducted inside the wooden canopy of the Department of Horticulture and Landscape Engineering / College of Agriculture and Forestry / University of Mosul during the agricultural season (2022-2023). to study the effect of spraying with different concentrations of calcium chloride (0, 500, 1000) mg. L-1 and spraying with gibberellic acid at concentrations of (0, 100, 200) mg. L-1 and the interaction between flowering growth of two varieties of Gladiolus hortulanus .They are Nova lux with yellow flowers and Trader Lux with red flowers . The corms were planted on 17/3/2022, then sprayed 30 days after planting the corms with three sprays and three concentrations of calcium chloride (0,500, 1000) mg.L-1 The plants were also sprayed with gibberellic acid, with three sprays and three concentrations (0, 100, 200), The period between one spray and another was two weeks. The spraying was done with gibberellic acid after 35 days of planting the corms. The study was carried out using a factorial experiment in the design of completed randomized sectors R.C.B.D within split plots with three replications, each experimental unit included (7) corms for each replicate. The yellow cultivar recorded the shortest period for color to appear in the first inflorescence, which amounted to 79.092 days, and the largest values in the fresh weight of the flower and the inflorescence, which amounted to 50.663 g. The diameter of the first flower reached 78.794 mm, the largest length of the inflorescence reached 41.285 cm, and the largest diameter of the flower stalk reached 9.294 mm. Also, there were no significant differences between the two cultivars in the characteristic of the number of florets per plant .The treatment with calcium chloride at both concentrations of 500 and 1000 mg.L-1 resulted in a significant increase in all studied traits. The treatment resulted in gibberellic acid at a concentration of 200 mg. L-1 resulted in a significant increase in all studied traits.
