| Abstract | ||
| The study was carried out at the lathhouse – Department of Hort., College of Agric., University of Baghdad on fall season/ 2007to investigate the influence of phosphorous and gibberelic acid levels on growth and flowering characters of Cheiranthus cheiri. Foliar applications of four levels of phosphorous 0, 20, 30, 60 g/l and three concentrations of GA3 0, 50, 100 m/l were applied . The results as follows: 1- the highest level of phosphorous fertilizer (50 g/l) increased significantly height of plants, number of branch/plant, dry weight of vegetative growth, leaves chlorophyll content and flowering stem diameter (33.33 cm., 32.56 branch/plant, 0.62 g., 1.757 mg/10g. and .41 mm.) respectively. While 3 g/l of phosphorous was effective in increasing number of leaves (235.5), leave area (57.0 cm2), leave phosphours content (0.378%) and dry weight of the inflourescense (1.26 g.). 2- The results showed that 100 mg/l of GA3 was significantly elevated phosphorous percentage in vegetative growth, number of inflourescense dry weight of inflourescense and stem inflourescense length (0.375%, 6.90 inlo./plant, 1.67 g. and 26.83 cm.) respectively. | ||
