Abstract
This experiment was conducted at a nursery belonging to Holy Najaf province during the period of 2009.The aim was to study the effect of three types of different medium and spraying of three concentrations of Licorice root extract on the vegetative growth and flowering of marigold plants.Randomized Complete Block Design (R.C.B.D) in three replicates was adopted .Least Significant Differences(L.S.D) of 0.05 probability level to compare the means. The resulted showed that culturing media had significant effect of the vegetative growth and flowering , the treatment (1max:2petmos) highest increase in number of branches , leaves , the leaf contents of total chlorophyll and number of flowers reaching (5 branch. plant-1 , 31.66 leaves. plant-1 , 15.18 mg. 100g-1 fresh weight , 38.88 flower. plant-1 ) respectively, also was sprinkle of extract of Licorice roots had a significant effect on the sprinkled plants with concentration 2gm.L-1 ) giving the highest increase in number of branches , leaves , the leaf contents of total chlorophyll , number of root branches , the dry weight of roots , number of flowers and weight of 100 seeds reaching (5.77 branch. plant-1 , 34.33 leaves. plant-1 , 14.64 mg. 100g-1 fresh weight , 17.11 branches of root. plant-1 , 5.61 gm , 43 flowers. plant-1 , 6 gm. 100 seeds-1) respectively, The interactions between agricultural medium and sprying of extract of Licorice roots gave significant differences in these characteristics
