“…Salinity decreased the plant growth and membrane stability index in a tomato plant [ 47 ]. Other studies have found a reduction in stem diameter in pistachio accessions under salt stress [ 48 ], similar to our findings. According to a previous study, the primary explanations for the reduction in stem diameter of pistachio seedlings were the limits of photo-assimilates accumulation and root function in water transport under salt stress [ 49 ].…”

Background Glycyrrhiza glabra L. is a medicinal and industrial plant that has gone extinct due to different abiotic stress caused by climate change. To understand how the plant-associated microorganism can support this plant under salinity, we collected sixteen Iranian accessions of G. glabra L., inoculated their rhizomes with Azotobacter sp. (two levels, bacterial treatments, and no-bacterial treatments, and grown them under salinity stress (NaCl levels; 0, and 200 mM). Results Two accessions of Bardsir and Bajgah significantly showed higher resistant to salinity, for example by increasing crown diameter (11.05 and 11 cm, respectively) compared to an average diameter of 9.5 in other accessions. Azotobacter inoculation caused a significant increase in plant height and crown diameter. Among studied accessions, Kashmar (46.21%) and Ilam (44.95%) had the highest rate of membrane stability index (MSI). Evaluation of enzyme activity represented that bacterial application under salinity, increased polyphenol oxidase (PPO) (0.21 U mg−1 protein), peroxidase (POD) (3.09 U mg−1 protein U mg−1 protein), and phenylalanine ammonia-lyase (PAL) (17.85 U mg−1 protein) activity. Darab accession showed the highest increase (6.45%) in antioxidant potential compared with all studied accessions under Azotobacter inoculation. According to principal component analysis (PCA), it was found that the accession of Meshkinshahr showed a more remarkable ability to activate its enzymatic defense system under salt stress. Also, three accessions of Meshkinshahr, Eghlid, and Ilam were categorized in separated clusters than other accessions regarding various studied treatments. Conclusion Analysis indicated that five accessions of Meshkinshahr, Rabt, Piranshahr, Bardsir, and Kermanshah from the perspective of induced systematic resistance are the accessions that showed a greater morphophysiological and biochemical outcome under salinity. This study suggested that, inoculation of with Azotobacter on selected accession can relieve salt stress and support industrial mass production under abiotic condition.

“…Mainly, plants differ greatly in their tolerance to salinity, as reflected in their different growth responses. The results of prior studies on the tolerance of P. vera are not in agreement, so that some suggested 'Ghazvini' as the most resistant tolerant rootstock [16,20], while others recommended 'Badami' [3,7,21] or 'Akbari' [22][23][24][25]. In previous studies on pistachio, salinity resistance, with some parameters [3,7,20], has been used to select resistant rootstocks only among P. vera species with medium salinity in very short duration, but the mechanisms have not been identified.…”

Osmolyte Accumulation and Sodium Compartmentation Has a Key Role in Salinity Tolerance of Pistachios Rootstocks

Physio-biochemical responses of pistachio varieties including Pistacia vera L. ‘Ghazvini’ (GH), P. vera ‘Ghermez-Pesteh’ (GP) and P. atlantica subsp. mutica (M) were assessed under salt stress to understand the common mechanisms of salt tolerance in two popular Pistacia species. In the experiment, half-sib seedlings of the varieties were subjected to high (100 mM) and severe (200 mM) levels of NaCl-induced salinity for 90 days. Growth, physiological, biochemical and ionic parameters in the roots and shoots of plants were measured in the experiment. Salinity markedly declined plant growth, and increased the number of necrotic leaves (NL) and leaf abscission. In terms of physiological responses, salinity reduced the relative water content (RWC), membrane stability index (MSI) and the concentrations of photosynthetic pigments, but increased carbohydrates and proline content in the leaves. MSI of the leaves was positively correlated with the concentrations of anthocyanins and carotenoids. Salinity increased sodium content in root and shoot tissues of the plants, and decreased potassium concentration and K/Na ratio. Among the rootstocks, GH had better performance on all parameters. Despite the high concentration of Na+ and low K/Na ratio in the shoots, the lowest number of NL was found in GH under both salinity levels. The results indicated that salt tolerance in GH was most likely related to compartmentation of Na+ ions. Finally, accumulation of osmolytes and sodium compartmentation were considered to be the most important mechanisms in the salt tolerance of pistachio rootstocks.

“…Among the studied rootstocks, 'Akbari' and 'Akbari' hybrid showed maximum final stem diameter, the final number of leaves, stem fresh weight, root, and stem dry weight compared to other rootstocks (Table 1 and 2). Raoufi et al (2019) revealed that ʽAkbari,' ʽAhmad-Aghai,' and ʽUCB-1ʹ had the lowest reduction in morphological and growth parameters under salinity stress. Also, they showed that these cultivars had the highest chlorophyll content, SPAD index, and soluble sugar content under salinity conditions.…”

“…However, some literature now exists concerning the superiority of 'Qazvini" (Hokmabadi et al, 2005), 'Akbari' (Adish et al, 2010;Akbari et al, 2018a;Goharrizi et al, 2020), and UCB-1 cultivar (Raoufi et al, 2020a) to salinity stress over the other P. vera rootstocks. However, in new researches, it has been determined that 'Akbari' rootstock is more tolerant to salinity than other rootstocks (Raoufi et al, 2019).…”
