EFFECT OF FOLIAR APPLICATION OF PRO.SOL NUTRIENT SOLUTION AND LIQUORICE EXTRACT ON GROWTH AND FLOWERING OF GERANIUM ( Pelargonium zonale L.)

Abstract

An Experiment was conducted during growing 1/7/2010 until 30/5/2011. in a private nursery at Hilla governorate (Jannata Ahlam), to study the effect of foliar application of PRO.SOL nutrient solution and Liquorice extract on growth and flowering of Geranium (Pelargonium zonale L). Cultivar Hans Rigler.was experiment included test of three concentrations of Nutrient Solution PRO.SOL (0.0,1.0 and 1.5) g.L­¹ and three concentrations of Liquorice Extract (0,1.5 and 3.0)g.L­¹. The Experiment conducted as a Factorial Experiment Randomized Complete Block Design (R.C.B.D).Duncans Multiple Range test was used at probability of 0.05 to compare means. Results revealed that the interaction between Nutrient Solution of PRO.SOL at concentration of (1.5) g.L­¹ and Liquorice Extract concentration of (3.0) g.L­¹ significantly increased in this parameters ( leaf area, leaf contents of total chlorophyll, total carbohydrate solubility, leaf content of nitrogen, phosphorus, zinc, number florets.plant­­¹, dry weight of florets and content flowers of anthocyanin by increasing percentage 35%, 25%, 19%, 15%, 71%, 44%, 48% and 27%, 31% and 32% and 46% and 41% for two period first and second respectively, Meanwhile, result revealed that the interaction between Nutrient Solution PRO.SOL at concentration of (1.5) g.L­­¹ and Liquorice Extract concentration of (1.5) g.L­­¹ significantly increased total branch number and shoot dry weight by increasing percentage 20% and 18% as compared to least values in the control treatment.
