Effect of Putrescine and Growing Media on Vegetative Growth and Chemical Constituents of Populus Euramericana Plants
This study was carried out at the Experimental Arid of the ornamental Horticulture Department, Faculty of Agriculture, Cairo University, Giza, Egypt during two successive seasons 2007 and 2008 to study the effect of growing media and putrescine on vegetative growth and chemical constituents of Populus euramericana. The results showed that, growing the plants in mixture from sand + clay medium and spray with putrescine at 50 ppm gave the highest values of plant height, number of leaves, total leaf area, diameter of stem, length of root, fresh and dry weight of leaves and stems, leaf concentration of chlorophyll a, b also carbohydrate % in the stems and roots, N% in the leaves and stems, P % in the leaves, stems and roots and K % in leaves, stems and roots. While, mix media and spray with putrescine at 100 ppm gave the highest values of root diameter , fresh and dry weight of roots, carbohydrate % in the leaves and N % in the roots
Keywords:Populus euramericana, growing media, growing mediavegetative growth and chemical constituents.
