Abstract EN

A study was conducted at the lath house in researchs station and agriculture experimental returns of college of agriculture - Kirkuk university - Al-sayada during September 2016 to April 2017 , to investigate the effect of pinching of plants (without pinching , pinching after one week of process of seedling ,pinching after 10 days of the first pinchined) , and spray plant of cycocel with twoconcentrations (0,1000) mg.L-1 , to growth and flowering of Chrysanthemum , the experience was designed according to Random Complete Block Design (R.C.B.D) with three replicate .

Results showed that pinching after one week of seedling was significantly superior to increase the leaves area (1265.56) cm2 comparison with control (1107.46) cm2, and the treatment of pinching after 10 days of the first pinched has led to delay the flowering date (35.3) days , and increased the length of stalk flower (4.08) cm against (34.37) days and (3.73) cm for the treatment of the comparison respectively.

The spray by concentration of 1000 mg.

L-1 of CCC was significantly superior to reduce the plant height (11.61) cm and increased wet weight of the flower (0.47) g compared to (12.43) cm and (0.44) g for the treatment of control respectively.
