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 (CaCl 2) 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 CaCl 2 with both concentrations resulted in a significant increase in the number of leaves and the spike length, The treatment with CaCl 2 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 CaCl 2 at 1000 mg.l-1 , while the violet cultivar ended their flowering 5 days when they were sprayed with SA interact with CaCl 2 at 1000 mg.l-l .

This experiment was carried out in the laboratory of the College of Agric. and Forestry at the University of Mosul, with the aim of studying some indicators of the cut inflorescences quality of two cultivars of the Chrysanthemum plant (Dendranthema grandiflorum Ramat.) with white and red inflorescences and delaying their senescence, as the bases of the cut inflorescences were immersed in the holding solution containing gibberellic acid at 0 and 25 mgl−1 and calcium carbonate at 0, 100 and 200 mgl−1 and their interactions. The Factorial experiment was conducted by a randomized complete block design. The results indicated that the cultivar with white inflorescences were recorded a significant increase in the values of the characteristics of the relative change in the inflorescences fresh weight and the amount of change in the inflorescences diameter, which reached to 87.79% and 87.37%, respectively, a significant increase was recorded in the volume of water absorbed by inflorescences and the inflorescences dry weight at the end of the experiment. The immersion in gibberellic acid at 25 mgl−1 resulted in a significant increase in the change of inflorescences fresh weight, change in the inflorescence diameter, volume of water absorbed of 10.19 cm3 and inflorescences dry weight 1.21 g. While immersion in calcium carbonate at 200 mgl−1 led to a significant increase in the amount of change in the inflorescences fresh weight, the change in the inflorescence’s diameter, and the inflorescences dry weight, which were 87.46%, 87.38%, and 1.270 g, respectively. It can be said that the inflorescences of the red variety that were added to the preservation solution of gibberellic acid at 25 mgl−1 and calcium carbonate at 200 mgl−1 recorded the largest significant values for the characteristics of the change in the inflorescences fresh weight, change in the inflorescence diameter, and the volume of water absorbed.
