Abstract

This study investigated the effect of using different concentrations of growth regulators Indole Butyric Acid (IBA) and different types of culture media included (sand, non- treated pinus brutia bark, non treated pinus brutia bark mixed with sand 1:1, pinus brutia treated bark, pinus brutia treated bark mixed with sand 1:1, peatmoss (Sphagnum Moss Peat), peatmoss mixed with sand 1:1) on rooting and growth cuttings of Ficus nitida.
Length & Diameter of longest root, root’s number, percentage of rooting, Roots dry weight, shoot length, shoot diameter, number of leafs, leafs area, shoots dry weight, leaves contents of (Nitrogen, Carbohydrate, Total content of chlorophyll & C / N ratio) as indicators of effects.
The use of the IBA growth regulator has improved most of the root and shoot’s growth properties, especially when using the concentration of 2000mg. L^-1, especially (length of the longest root, Root diameter, number of secondary roots, dry weight of roots, length & diameter of the longest shoot, Leaf number, leaf area, total chlorophyll and dry weight), while the concentration of 3000mg. L^-1 to improve the content of leaves of nitrogen and carbohydrates. The cultivation and growth of cuttings in the Pine bark media significantly increased the average of root length, diameter & rate of Nitrogen in leaves. Using (treated Pine bark + sand 1:1) media caused an increase in the leaf area, Carbohydrates rate in leaves and the ratio of C / N.
