“…Salinity has a significant impact on plant metabolism, generating ion toxicity, osmotic stress, mineral inadequacies, and physiological, biochemical, and metabolic alterations, eventually influencing plant growth, development, and productivity [10,11]. Accumulation of higher concentrations of inorganic cations such as sodium, magnesium, and calcium, and anions such as chloride and sulfate, disturb the membrane potential [12]. The high concentration of salts in the soil has a destructive effect on the cell membrane's integrity, photosynthetic reactions, activation of several proteases, and absorption of nutrients [13].…”

Salt stress is one of the major constraints affecting plant growth and agricultural productivity worldwide. Sorghum is a valuable food source and a potential model for studying and better understanding the salt stress mechanics in the cereals and obtaining a more comprehensive knowledge of their cellular responses. Herein, we examined the effects of salinity on reserve mobilization, antioxidant potential, and expression analysis of starch synthesis genes. Our findings show that germination percentage is adversely affected by all salinity levels, more remarkably at 120 mM (36% reduction) and 140 mM NaCl (46% reduction) than in the control. Lipid peroxidation increased in salt-susceptible genotypes (PC-5: 2.88 and CSV 44F: 2.93 nmloe/g.FW), but not in tolerant genotypes. SSG 59-3 increased activities of α-amylase, and protease enzymes corroborated decreased starch and protein content, respectively. SSG 59-3 alleviated adverse effects of salinity by suppressing oxidative stress (H2O2) and stimulating enzymatic and non-enzymatic antioxidant activities (SOD, APX, CAT, POD, GR, and GPX), as well as protecting cell membrane integrity (MDA, electrolyte leakage). A significant increase (p ≤ 0.05) was also observed in SSG 59-3 with proline, ascorbic acid, and total carbohydrates. Among inorganic cations and anions, Na+, Cl−, and SO42− increased, whereas K+, Mg2+, and Ca2+ decreased significantly. SSG 59-3 had a less pronounced effect of excess Na+ ions on the gene expression of starch synthesis. Salinity also influenced Na+ ion efflux and maintained a lower cytosolic Na+/K+ ratio via concomitant upregulation of SbNHX-1 and SbVPPase-I ion transporter genes. Thus, we have highlighted that salinity physiologically and biochemically affect sorghum seedling growth. Based on these findings, we highlighted that SSG 59-3 performed better by retaining higher plant water status, antioxidant potential, and upregulation of ion transporter genes and starch synthesis, thereby alleviating stress, which may be augmented as genetic resources to establish sorghum cultivars with improved quality in saline soils.

“…In determining the quality of halophyte forage, salts content of soil has an important role that leads to less shoot proteins content (Nikalje et al, 2019, Temel andKeskin, 2019). Decreased CP values in saline conditions could be due to reduction in nutrient uptake from saline soils, which lead to reduced synthesis or enhanced degradation of proteins, low amino acid availability, and denaturation of enzymes associated with protein synthesis (Hedayati-Firoozabadi et al, 2020).…”

“…Generally, halophytes contain considerably high ash levels (Zare et al, 2019). It has been stated that Na + , K + and Clare the most frequent ions contributed in ash content of the halophytes (Waldron et al, 2020), however species belongs to Amaranthaceae had acceptable free oxalates contents (Hedayati-Firoozabadi et al, 2020). This is focused on whether or not higher ash content in plant tissue is better for good quality forage.…”

“…At the flowering stage, sampling was done for fresh and dry weights. This time was considered to achieve the best quality of sorghum forage (Atis et al, 2012;Hedayati-Firoozabadi et al, 2020). For this purpose, one square meter was taken from each plot, and weighed immediately.…”

Information on the impact of salinity of irrigation water on soil moisture and salt content is scant in the literature. Therefore, in the present study, growth of sorghum as well as soil moisture and salt content were investigated as affected by irrigation water salinity. In this experiment, the effect of three salinity levels of irrigation water, i.e., 2, 7 and 14 dS m-1 was monitored on sorghum growth, and changes in soil moisture and salinity of soil saturated extract during the growing season. Irrigation water salinity, depending on the intensity of stress, reduced forage yield, so that 7 and 14 dS m-1 salinity decreased the fresh weight by 11% and 45% and the dry weight by 17% and 62%, respectively, compared to those in non-saline conditions. At two soil depths (0-30 cm and 30-60 cm), the lowest moisture content was observed under non-saline conditions and the highest at 14 dS m-1. The salinity of soil saturated extract was also increased with increasing salinity of irrigation water. By applying salinities of 2 and 14 dS m-1, soil salinity decreased and increased by the end of the growing season, respectively. However, soil salinity in 7 dS m-1 treatment was decreased first and then increased until the end of the growing season. At the end of the growing season, the average soil salinity in 7 and 14 dS m-1 treatments was 1.8 and 1.4 times, respectively, higher than that of the irrigation water salinity. In a nutshell, in saline conditions, more moisture remains in the soil, which may help sustain the of growth of halophytes to some extent.
