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 chlorophyll
intensity in the leaves when picking flowers 54.958 (SPAD), the nitrogen percentage is 1.212%, the
phosphorus is 0.383%, the potassium is 1.807% and the concentration calcium is 819.05 mg.l-1
. The plants
sprayed with salicylic acid at 250 mg.l-1 had a significant effect in recording the largest values of all
studied traits. The treatment with calcium chloride with both concentrations of 500 and 1000 mg.l-1
resulted in a significant increase in the chlorophyll intensity in the leaves when picking flowers. The
treatment with calcium chloride at 1000 mg.l-1 gave the largest values for the calcium concentration is
831.66 mg.l-1 . The treatment with calcium chloride at 500 mg.l-1 caused to increase the nitrogen
percentage 1.232%, phosphorus 0.419% and potassium 1.851%.
