Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Agriculture - Department of Ornamental Horticulture Summary: This study was concluded in the Experimental Nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University, during the two successive seasons 2014 and 2015. This work was aimed to evaluate the effect of chemical and organic fertilization treatments on the vegetative growth and biochemical constituents of Chamaedorea elegans, Mart. plants grown under different light intensity levels. The plants were placed under full sunlight, lath house and green house conditions provided light intensity levels of 100, 30 and 21% respectively. Plants grown under the three levels of light intensity were fertilized every 3 weeks with either chemical lNPK (Kirstalon, 19-19-19) at the rate of 2 and 4 g/pot or organic Humic Acid (HA) applied as a soil drenching at the concentration of 3 and 6 ml/L, in addition to the control plants. The Results showed that in most cases, the lower light intensities levels (30 or 21 %) significantly increased plant height, number of leaves/plant, stem diameter, root length, number of roots/plants, fresh and dry weights of shoots and roots as well as increased the contents of chlorophyll a, chlorophyll b, total chlorophylls (a + b), carotenoids in leaves, total carbohydrates in roots, N and P% in roots, K % in both shoot and roots and indoles content in leaves (with superiority effect of light intensity of 21%) as compared with full sunlight (100%). while they reduced the contents of total carbohydrates, N and P% in shoots as compared with full sunlight (100%). In both seasons, phenols content in leaves were significantly higher in plants grown under light intensity of 30 % than those grown under other light intensities (100% or 21%)
