foliar spray at 400 and 600mg increased stem
length, number of new leaves/plant and stem
diameter, leaf area and plant dry weight (Alkhateeb,1996
and Hegazi, et al., 2002).
The aim of the present work is to find out the
effect of water stress, Phosphorus, and culture
media on some morphological, physiological
characteristics of transplanting pistachio, under
water stress conditions

two years old during 2009 were selected. The
experiments were started in 10 th April 2009, as
transplants were grown in pots each of ( 7.5kg)
weight, filled with three media cultures (river
loamy soil, 1/1 river loamy soil to peatmoss and
2:1 river loamy soil to peatmoss), plants were
irrigated while 25% or 50%, of soil available
water depleted (figer.1, 2, 3) as adapted by Abo-
Taleb, et al., (1998) and Caser (2008). Five p2o5
concentrations (0,100, 200, 300, 400mg.P.L -
1 .Pots -1 ) were applied to the pots. The following
measurements were recorded on 10 th October
2009.
