| Abstract | ||
| Factorial experiment was carried out on the nurseries of the College of Agriculture and Forestry at University of Mosul /Iraq. During the growth period 2007 to study the impact of apricot seeds at soaking in three concentrations of gibberellic acid 0,500,100 mg GA3/l for 24 hors, fertilization with (NPK) fertilizers as solutions at three levels 0,100,200 mg NPK.L-1 and spraying the transplants with a mix of gibberellic acid and Kinitin 1:1: at three concentration levels of 0,150,300 mg.L-1 besides studying the interactions between the investigated factors. The results are briefed that soaking apricot seeds with 1000 mg GA3.L-1, fertilizing with NPK especially at the concentration 200 mg NPK.L-1 and Foliar spraying with the mix of gibberellic acid and Kinitin at 300 mg .L-1 resulted in a significant increase in the number of leaves ,leaf surface area, number of branches and concentration of chlorophyll and N,P,K elements in the leaves. For maximizing the growth of Apricot rootstocks , it is advised to the treatment of (1000 mg GA3 .L-1 + 200 mg NPK .L-1+300 mg (gibberellic acid : Kinitin .L-1) that led to an increase in number of leaves and concentration of NPK elements in the leaves. | ||
