The experiments are implemented in the lath house of the Horticulture and Landscaping Department, College of Agriculture, Basrah University for season 2010-2011 in order to investigate the effect of spraying of Thiamine and Ascorbic acid on vegetative and flowering growth of Carnation Dianthus caryophyllus L.

The experiment includes studying the effect of spraying with three concentrations of Thiamine (0,25,50) mg/l and three concentrations of Ascorbic acid (0,25,50) mg/l and the interaction among them.

A Complete Randomized Design is used with three replicates; the means are compared by using revised least significant difference test at 0.05 probability.

Results show that the plants treated with 50 mg/l thiamine causes a significant increase in most vegetative characteristics and plants treated with 25 or 50 mg/l thiamine causes a significant increase in most of flowering characteristics studied .Treatment with Ascorbic acid concentrations 50 mg/l causes a significant increase in plant height and most of flowering characteristics
