Pistacia vera cv Badami-e-Riz is the most important and popular rootstock in Iran, which tolerate salinity soil and phytophthora fungi but its root is less affected. In addition this rootstock is susceptible to excessive B and water deficient. This rootstock has a taproot rooting system without any lateral root. So this study was conducted to evaluate the effects of various concentrations and application methods of polyamines on root regeneration of transplanted bare-rooted ‘Badami-e-Riz’ pistachio rootstocks.The result showed that spermidine at concentration of 2 mM as foliar application method significantly enhanced root length and root diameter in ‘Badami-e-Riz’. Furthermore, the fresh weight of root was increased by 4 mM spermidine by foliar application and 2 mM spermidine by interaction of root tip cut and root dip method, significantly increased dry weight of root and root number in ‘Badami-e-Riz’. Besides, by the use of these chemicals, the survival percentage of seedlings was maintained in higher value. Results suggested that polyamine application was effective to increase lateral root formation and improved root regeneration. Therefore, it would be useful to help the survival of seedlings following transplanting.
