Abstract: 

A factorial greenhouse experiment as completely randomized design with six replications was conducted to Study the effects of potassium and salinity application on morphological and physiological parameters of pistachio seedling (cv. Badami-e-Zarand) in perlit. Treatments were 2 levels of K (0 and 1 mM KNO3) and 3 levels of salinity (0, 100 and 200 mg NaCl kg-1 soil). Prolin and redusing sugars contents whit 3 replications and on two separate time (3 and 6 days after salinity application) measured. A factorial split analyzed to test the trend of this factors so that salinity×pottasium and time were as main and sub factors respectively. Results showed that as salinity increased shoot and root dry weights 17% and 15% increased, respectively. As increasing K consentration from 0 to 1 mM, increased dry weight shoot from 0.885 to 1.007 per pot.1 mM K application increased the leaf number and stem height. As salinity increased significantly increased Na and decreased Mg of plant. Prolin and redusing sugars contents increased three days after application of salinity treatments while K decreased prolin consentration. redusing sugars content significantly affected by time factor so that redusing sugars consentration redused after 3 days but it wasn’t correct about prolin content.
