| Abstract : This study was conducted in the Lath house of the Horticultural Department, College of Agriculture – University of Baghdad during 2011 – 2012 growing seasons to investigate the influence of pruning and some growth stimulator on vegetative growth characteristic of mandarin cv. Clementine budded on Sour Orange's root stock.The one years old Clementine transplants transport to poly ethylene bags (weight 10 Kg) in lath house under spraying irrigation system.The transplants was pruned in three levels(Without pruning، one branch/plant ،two branches/ plant), and treated monthly by foliar application of GA3in concetration 50 and 100 mg/L , Naa in concetration 5 and 10 mg/L and Tryptophan in concetration 50 and 100 mg/L was foilar application every two weeks.the feild experment was conducted as Split- Plot design that pruning present main plot while foilar treatments present sub-plot .The experimental results shows Pruning had a significantly increase effects in plant hieght and chlorophyll leaves content , while had no significat effect on leaf area. Foliar application of growth stimulators lead to significant increase in most vegetative characters especially in high concetration of growth stimulators. | ||
