The experiments are implemented in the lath house of the Horticulture and<br /> Landscaping Department, College of Agriculture, Basrah University for<br /> season 2010-2011 in order to investigate the effect of spraying of Thiamine<br /> and Ascorbic acid on vegetative and flowering growth of Carnation<br /> Dianthus caryophyllus L. The experiment includes studying the effect of<br /> spraying with three concentrations of Thiamine (0,25,50) mg/l and three<br /> concentrations of Ascorbic acid (0,25,50) mg/l and the interaction among<br /> them. A Complete Randomized Design is used with three replicates; the<br /> means are compared by using revised least significant difference test at 0.05<br /> probability. Results show that the plants treated with 50 mg/l thiamine<br /> causes a significant increase in most vegetative characteristics and plants<br /> treated with 25 or 50 mg/l thiamine causes a significant increase in most of<br /> flowering characteristics studied .Treatment with Ascorbic acid<br /> concentrations 50 mg/l causes a significant increase in plant height and<br /> most of flowering characteristics
