| Abstract | ||
| The study was conducted in Lath house of department of Horticulture and landscape Design/ College of Agriculture/ University of Kirkuk/ Shurao, for the period from 1 October 2018 to June 2019 to investigated the effect of priming in Salicylic acid at three concentration of (0, 150, 300) mg. L-1 for 24 hours before planting and spray with three concentration of Gibberellic acid (0, 100, 200) mg. L -1 on growth and flowering of Iris hollandica, cultivar Gemengd, factorial Randomized Complete Blok Design (R.C.B.D), results show that effect of soaking of iris bulbs with different concentrations of salicylic acid before planting significantly in most vegetative and floral qualities, soaking resulted in a concentrations of 150 mg. L-1 length of stalk (65.01) cm, while soaking at a concentrations of 300 mg. L-1 gave the longest leaf (131.34) cm, the largest diameter of the flower (12.20) cm, and vase life (9.55) significant in most vegetative and floral qualities, spraying at 100 mg. L -1 concentration, gave height of flower diameter (12.07) cm, when sprayed at a concentration of 200 mg. L-1 the highest number of leaves(5.38) leaves. Plant -1, the longest leaf length (130.18) cm, flower stalk (68.01) cm, and the largest vase life (9.77) days, interaction between salicylic acid and gibberellic acid the effect of control treatment of salicylic acid and spraying at a concentration of 200 mg. L-1 of gibberellic acid in obtaining the highest number of leaves (5.66) leaf. Plant -1 and longer of stalk (69.00) cm, soaking at a concentration of 300 mg. L-1 gave the longest leaf (134.11) cm, the largest flower diameter (12.50) cm, the largest vase life (11.00) days | ||
