A study was conducted at the lath house, Department of Horticulture and landscaping design / college of Agriculture/ University of Kirkuk / Shurao , during )15/ 9/ 2017(to (15/4/2018) the study included effect of salicylic acid spraying at concentrations of (0,150) mg .

L -1, in growth and flowering of three cultivars of Chrysanthemum plants: Pitt White(white flowers), Hanks yellow (Yellow flowers)and Blanchett orange (Red flowers), The following results were showed: 1-Effect of spraying salicylic acid at a concentration of 150 mg.L - 1 morally in improving growth flowering and root, which resulted in a significant increase in plant height(16.85) cm , total chlorophyll content (37.76 )mg .

g -1 fresh weight ,number of leaves (580) leaves.plant-1 ,dry weight of the vegetative total( 7.52) g , number of inflorescences ( 104.44) inflorescence.plant-1 and the dry weight of the inflorescence and roots (0.032 and 3.79) g respectively.

2- Contrast cultivars significantly in all studied traits , Pitt White superior in giving the highest rate of plant height (18.94) cm , number of leaves (776) leaves.plant-1 and the dry weight of the total vegetative (7.27) g , number of inflorescences ( 117) inflorescence.plant-1 , and the longest duration of coordination age (75.07) days, while the highest content of chlorophylls total Blanchett orange (43.50) mg .g -1 fresh weight and the highest dry was in weight for inflorescence and roots (0.034, 4.10) g respectively, but it took the minimum time of age coordination (55.72) days, Hanks yellow has the lowest plant height (14.50) cm , total chlorophyll content (28.87) mg .g -1 fresh weight , dry weight of total the vegetative (6.21) g and number of inflorescences (87) inflorescence.plant-1.

3- The cultivars differed in their active response to spraying with salicylic acid 150 mg.L-1 , Pitt White was significantly higher in plant height (19.16) cm, number of leaves (856) leaves.plant-1 , number of inflorescences (124) inflorescence.plant-1 and took the longest coordination (75.59 )days, while the superiority of the cultivars Blanchett orange in total chlorophyll content (45.56) mg .

g- 1 fresh weight and dry weight of total vegetative and inflorescence (8.09, 0.034) g respectively ,While Hanks yellow gave the highest dry weight of roots (4.66) g when spraying with salicylic acid at 150 mg.L-1.
