J. Duhok Univ. Vol.13, No.1, (Agri. And Vet. Sciences) Pp 25-35, 2010 Results in (Table 6) revealed that water levels significantly affected the leaf dry weight (1.49g). The obtained results of media cultures displayed that treated pistachio transplant with 2:1river loamy soil/peatmoss resulted in significant increase in leaf dry weight(1.71g). Pistachio transplant treated with P concentrations significantly increased leaf dry weight (1.66g), especially when 200 mg.p.L -1 .pots -1 was applied as compared to 400mg.L -1 .pots -1 . The obtained results revealed that 25%water +2:1river loamy soil/peatmoss was superior over that of 50% water+1:1river loamy soil/peatmoss in leaf dry weight(1.89g). The combination between water levels and phosphorus concentration displayed that 25%water and 200mg.p.L -1 .pots -1 appeared to be the most potent treatment (1.87g). While the lowest leaf dry weight(1.15g) was coincide with 50%water +400 mg.L -1 .pots -1 . Results of media cultures and P concentrations interaction manifested that treated with 2:1river loamy soil/peatmoss and 200 mg.p.L -1 .pots -1 resulted in the highest leaf dry weight(1.88g). The lowest leaf dry weight was observed with1:1river loamy soil/peatmoss and untreated check (0.50g). Results of water levels, media cultures, P concentrations and their interaction manifested that pistachio transplant treated with that 25% water +2:1river loamy soil/peatmoss and 200mg.p.L -1 .pots -1 was the most potent treatment as it gave the highest leaf dry weight (2.10g). While, the lowest leaf dry weight was coincide with that 25%water +1:1river loamy soil/peatmoss and control (0.50g). Increase in height, stem diameter, leaf number, leaf area, vegetative fresh weight and dry weight were attributed to medium mixture of 2:1river loamy soil to peatmoss which provided optimal root growth ambient conditions of aeration, water availabilities, pH, organic content and adequate phosphorus and other nutrients. Water stress was found to affect every aspect of plant growth. Some of these effects were related to decrease in turgid. Water potential and osmotic potential, water availability. Several of evidences indicate that there are changes in the photosynthetic pigments and mechanisms in the chloroplasts and that change in ultra structure may occur under water stress. Phosphorus is a macronutrient that is used in the sugar phosphates that store energy and is also necessary in the production of wood.
