Abstract

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
