The pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae) is a major pest of pistachio trees, Pistacia vera L. (Sapindalis: Anacardiaceae) throughout pistachio-producing regions in Iran. Different density levels of A. pistaciae nymphs were maintained on pistachio trees by different insecticide dosages to evaluate the relationship between nymph density and yield l...

Pistacia vera L. is a decidious tree. To investigate the influence of soaking seeds in polyamines (PAs) spermine (Spm), spermidine (Spd) and putrescine (Put) on seed germination and enhancing lateral root development of ‘Ghazvini’ pistachio seedling rootstock, the experiment were carried out in petri dishes and plastic bags. Seeds were soaked in PAs( Spd, Spm, and Put) at three concentrations( ...

To explore the free radical scavenging properties of crude ethanolic extract of galls, bark, leaves, roots of Pistacia integerrima and its subsequent solvent fractions viz., n-hexane, chloroform, ethyl acetate and methanol against 1, 1-diphenyl-2-picrylhydrazyl (DPPH) stable. In vitro DPPH based free radical was employed using querceitin as standard antioxidant while methanol as negative contro...

Oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. As the antioxidant effects of some species of Pistacia have been reported, the protective effects of Pistacia vera L. gum extract (0.1-0.5 g/kg) on oxidative damage following cerebral ischemia were studied in rats. Ischemia was induced using four-vessel occlusion model and evaluated using measurement of m...
