Abstract

Introduction: Soil and water salinity in many parts of the world, especially in arid and semiarid areas, growth limiting factor. In recent years, much research into adapting the plants to environmental stresses such as salinity. The Pistachio plant salt-tolerant, but the yield on high salinities and decreases severely affected. The present study was to the effect of salinity on the Relative Growth Rate, Net Assimilation Rate, Leaf weight Ratio three cultivars of pistachio(Akbari, Aghaei, and Kalle-Ghuchi). Understanding the mechanisms of tolerance of crop plants to high concentrations of NaCl in soils may ultimately help to improve yield on saline lands. Esmaeilpour et al. (2019) observed that drought and Salinity stress significantly reduces photosynthesis and stomatal conduction in pistachio trees, which is the fastest stomatal response of the plant to soil moisture conditions. The physiological response of the plant to the availability of soil water such as stomatal conduction and vascular sap movement is always a better indicator of plant moisture conditions compared to soil moisture and suction (Parry, 2014). Material and methods: The experiment was arranged in a randomized complete block design consisting of a 3×4 factorial combination of three pistachio cultivars and four salinity levels (1, 5, 10, and 15 dS/m sodium chloride) with three replications. Four pots were selected and harvested from each experimental unit before and after 30 and 60 days of salinity application. Then RGR, NARw, LWR calculated (formula 1, 2, 3). Data were analyzed by SPSS software and mean comparison was performed using the Duncan test at a 5% level. Excel software was used to draw charts. Results and discussion: Aghaei have a high amount of Relative Growth Rate, Net Assimilation Rate, Leaf weight Ratio, and Root length at the highest levels of salinity (15 dS/m) and Akbari due to having less amount of Relative Growth Rate, Net Assimilation Rate, Leaf weight Ratio, and Root length sensitive to salinity. Root density was evaluated as an indicator of Root morphology. The effect of salinity on Root length and density is shown in Table (3). Increasing salinity treatment from 1 to 15 dS/m, Root length, and density decreased significantly at a 5% probability level. Conclusions: According to the results, salinity has a significant and direct effect on the Relative Growth Rate, Net Assimilation Rate, and Root morphology of three pistachio cultivars and is not significant in terms of Leaf weight among the studied cultivars.
