| Abstract | ||
| Babylon . to find out the effect of two cultivars of pear scions (Muntakhab al-zaufrania and Lecount) and treatment of the seedlings with GA3 (0,150,300) mg/L and foliar nutrition with Premium (0, 0.5 , 1) gm/L in the vegetative growth parameters of pear seedlings transplanted on Pyruscalleryana pears using factorial experiment in R.C.B.D with 3 Replicates . Means were compared using L.S.D at 0.05 , The Results shows that Muntakhab al-zaufrania cultivar gave higher percentage of budding success and shoot length compared with lecount cultivar . Treatment pear seedlings with concentration of GA3 (150 mg/L) gave highest values of shoot length , leaf area , dry weight percentage of leaves and leaves mineral content of (N,P,K) compared with the control treatment . Treatment pear seedling with concentration of nutrient solution (Premium at gm/L) gave significant increase in all vegetative growth characteristics and nutrient element in leaves (N,P,K). The interaction between GA3 treatment at 150 mg/L and foliar nutrition with Premium at 1 gm/L gave a signification effect in all vegetative growth characteristics and nutrient element in leaves (N,P,K) .The interaction between cultivar of muntakhab Al-zaufrania and foliar nutrition with Premium at 1 gm/L gave a significant increase in shoot length , leaves area , chlorophyll content and dry weight percentage in green part and the nutrient elements percentage in leaves and (P) compared with the other treatment .The interaction between lecount cultivar and foliar nutrition with premium at 1 gm/L gave highest percentage of K. The interaction between cultivar of muntakhab Al-zaufrania and GA3 treatment at 150 mg/L gave a highest rate in the vegetative shoot length (158.844 cm). The interaction between muntakhab Al-zaufrania cultivar and GA3 treatment at 150 mg/L and foliar nutrition with Premium at 1 gm/L gave a significant increase in the vegetative shoot length rate . | ||
