| Abstract : This experiment was conducted at Agriculture college – Kufa university during the agricultural season 2010 to study the effect of different levels of calcium in nutritious solution concentrations in the vegetative and root growth characters in the climber plant of Cat's Paw Begnonia purpurea L. , in hydroponics . The randomized complete block design (R.C.B.D) include six levels from degrees of calcium concentrations , ( 0 , 830 , 1650 , 2500 , 3330 , 4150 ppm Ca) , with eight replicates , Duncan’s Multiple Range Test on probability of 0.05 was adopted to compare the means . Results showed that calcium concentrations in the environment gave significant raise in the studied characteristics . Increase Ca levels to 2500 ppm Ca , 3330 ppm Ca used significant increase in length of plant , number of branches , leaves area , root dry weight and the leaf contents of total chlorophyll , which reaching ( 45.5 , 44.25 cm ; 3.55 , 3.75 branch .plant-1, 517.5 , 560 cm2 , 3.78 , 3.82 gm , 34.25 , 32.5 mg. 100 g-1 fresh weight) respectively. Also increase Ca level to 2500 ppm gave highest percent in dry matter which reach (13.45%) , Whereas Ca level to 3330 ppm gave the highest number of root branches reaching (46.5 branch .plant-1) , The highest level of Ca 4150 gave the highest Ca percentage age in plants leaves (2.51%) | ||
