| Abstract | ||
| An experiment was conducted on Rosa. Sp. For the year 2010-2011 in the lath house / Al. Qadisyia University. to study the effect of giberellic at the concentration of (0 , 100 , 200 , mg/L) and phosphate levels (0 , 25 ,50 Kg/Donum). On veg atative and. Flower growth. The parameters studied were, height plant, number of branches, leaf area, per centage of dry weight and number of flowers. The results were as follow: - Gibberellic acid at the concentration of 200mg/L Led to asignificantly increase in height plant , per centage of dry weight and number of flowers but it. No significant increase in the number of branches and leaf area. - At another side, high levels of phosphate positively affected vegetative growth except the leaf area. - Interaction between the GA3and phosphate levels had significantly positive effect on the all characters except the number of flowers. | ||
