Abstract

Budding and grafting are the strategies employed to combat unfavorable environmental conditions and improve some physiological defects in the Pistacia vera tree. Drought and salinity stresses are the most prominent adverse conditions encountered in pistachio production. It has been observed in different studies that various pistachio rootstocks can be used to ameliorate the effect of those two stresses. Besides, rootstock has a role in some physiological performances of pistachios such as nutrient uptake and photosynthesis. Furthermore, nut blank, unsplit nut, and alternate are three physiological disorders found in pistachio. Relationships have been found between the degree of these physiological disorders and the rootstock effect. The impact of rootstock on drought and salinity stresses, physiological performances, and physiological disorders in P. vera will be discussed in this review.
