Abstract
The aim of this research was evaluate the seedling behavior of among Pistacia species can be used as rootstock in pistachio. Differences in stem diameter were observed among the species. The thickest stems were developed by P. atlantica (5.67 mm), P. vera cv. ‘Qazvini’ (25.47mm) and ‘Badami-e-Riz-e-Zarand’ (5.13 mm) whereas the thinnest stems were measured in P. atlantica subsp. kurdica (3.48 mm), P. atlantica subsp. mutica (3.52 mm) and P. atlantica subsp. cabulica (3.84 mm). P. atlantica produced more leaf number per seedling than the other species and cabulica had the most SPAD index. The correlation between various morphological traits showed that a few growth characters were significantly correlated with echophysiological. However, leaf dry weight was in significant correlation with RWC for P. vera cv. ‘Badami-e-Riz-e-Zarand’ and ‘Sarakhs’, fresh weight of leaf for P. khinjuk and P. atlantica subsp. kurdica, shoot dry weight was in correlation with stomata resistance for P. atlantica subsp. mutica and cabulica and leaf fresh weight and dry weight negatively correlated with SPAD for P. atalntica.
