الملخص EN

The experiment conducted as Factorial experiment in private farm in Babylon province from 1/6/2015 until 30/1/2016 to study the effect of spraying of Vitamin C with three concentrations (0,100 and 200) mg L-1 , three concentrations of Glutamic acid (0, 100 and 200 ) mg L-1 , three concentrations of BA (0, 20 and 40) ml L-1 and their interaction on some physiochemical characters of Chrysanthemum hortorum Hort.

By three spraying on month between each spray and second spray.

Complete Randomize Design (C.R.D ) with three replicates was using.

Means were compared using probability range 0.05.

Spraying with all individual treatments significantly increased all studied characteristics compared with control treatment.

Vitamin C (200 mgL-1) significantly increased branches number per plant , leaves number per plant, leaf area, flower diameter, flower stalk diameter, the percentage of protein, and GA3.

Percentage of vegetative dry weight (20.75) and cytokinin (29.75mM) increased with Glutamin( 200 mgL-1) and BA(40 ml L-1) respectively.

Results revealed that the interaction between plants treated with (Vitamin C 200 + Glutamic acid 200+BA40) increased branches number /plant ,leaves number /plant, Percentage of vegetative dry weight, flower diameter, the percentage of Protein , IAA, GA3 and cytokinin.

Leaf area and flower stalk diameter increased with (Vitamin C 100 + Glutamic acid 200+BA 40) and (Glutamin 100+BA 40 ) respectively compared with the control treatment.
