| Abstract | ||
| An experiment was conducted at Faculty of Agriculture /University of Kufa in the growing season of 2012/2013 to evaluate the effect of growth regulator GA3 and nutrient solution on some growth and flowering characteristics . Factorial experiment (3x3) was designed with two factors, first three concentrations of Gibberilic acid (0,100,and 200) mg.L-1 second factor included three concentrations of nutrient solution (0,2,and 4) g.L-1 according to Randomized Complete Block Design (R.C.B.D). The average of treatments were compared by using least significant difference test on 0.05 probability level. Results showed that spraying with gibbrellic acid and nutrient "KomBe" interaction solution gave significant effect on vegetative, root and flowering and their growth characteristics,. The interaction treatment 200 mg.L-1 of gibberellins and 4 g.L-1 of nutrient solution in creased plant height, number of side branches, number of leaves, dry weight of shoots, leaf content of total chlorophyll, leaf content of the total soluble carbohydrates, length of tallest root, dry weight of root, flower stalk number and flower stalk and carotenoid pigments(32.10 cm, 7.33 branch/plant, 77.87 Leaf/plant, 24.15 mg.100gm Fresh weight, 52.43 mg.gm-1 dry weight, 28.85 gm, 6.41 gm, 17.00 Cluster/plant, 18.90 cm, 3.90 mg) contents compared with control treatment length of key word that gave the lowest values of the same characteristics(19.63 cm, 2.67 branch/plant, 30.23 Leaf/plant, 6.22 gm , 5.50 mg.100gmFresh weight, 25.94 mg.gm dry weight, 8.11 gm, 2.28 gm, 5.33Cluster/plant, 5.47 cm, 1.76 mg). | ||
