Abstract
This experiment was carried out in the Green net house at the College of Agriculture and Forestry for the period from April to September 2019, with the aim of assessing the response of three cultivars of Gladiolus X hortulanus L. for treatment with (SA) at a concentrations of zero and 250 mg.l-1 as well as treatment with (CaCl2) concentrations are zero, 500 and 1000 mg.l-1 sprayed on the vegetative growth twice. The results indicated the following: The red cultivar recorded the largest height, the number of leaves, shortest the period from planting to the inflorescence bud initiation and longest vase life, While the white cultivar recorded the largest value of spike length. The plants sprayed with SA had a significant effect in recording the largest values of all studied traits except for the duration from planting to the inflorescence bud initiation, which decreased significantly. The treatment with CaCl2 with both concentrations resulted in a significant increase in the number of leaves and the spike length, The treatment with CaCl2 at 1000 mg.l-1 gave the largest values for the plant height and the vase life. showed that red and white cultivars produced flower that fall within a special grade when they were sprayed with SA or did not interact with spraying with CaCl2 at 1000 mg.l-1, while the violet cultivar ended their flowering 5 days when they were sprayed with SA interact with CaCl2 at 1000 mg.l-l.
