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( ...

in the course of studies about fungi associated with pistachio (pistacia vera l.) die-back disease in the ghaen region of southern khorasan (iran), one species of geosmithia was found. the isolates were identified as geosmithia lavendula (raper & fennell) pitt based on its morphological and molecular properties. the genus geosmithia (ascomycota: hypocreales) is belonging to mitosporic filame...

Classification within the genus Pistacia has been based on leaf morphology and geographical distribution. Molecular genetic tools (PCR amplification followed by restriction analysis of a 3.2-kb region of variable chloroplast DNA, and restriction fragment length polymorphism analysis of the Pistacia cpDNA with tobacco chloroplast DNA probes) provided a new set of variables to study the phylogene...
