“…The results of this study also showed that 0.75-mM SA concentration had the greatest effect on the modulation of the negative effect of salinity, which led to the highest dry weight of shoots and roots, whereas SA application at 1.5-mM concentration in some cases had a negative effect on plant growth. This increase in yield by SA may be due to its physiological roles, including ion uptake, and photosynthetic processes [17,25], which directly or indirectly regulate the function of plants. The optimum concentration of SA for most plants is between 0.5 to 1 mM and can cause tolerance to abiotic stress.…”

“…One of the reasons for the decrease in growth and yield of quinoa under salinity stress is a change in the balance of phytohormones [6,17]. The use of plant-growth regulators (PGR) significantly causes hormonal balance in plants in saline conditions and thus increases the plant tolerance to salt stress [11].…”

“…Studies show that SA regulates unilateral internal K + channel inactivation, which in turn plays a role in ionic balance, aperture closure, photosynthesis, enzymatic activity, improvement of protein and carbohydrate synthesis, and product quality [8]. Because SA also plays a role in regulating redox, high concentrations of SA may reduce stress tolerance through impaired redox status [8,17]. Hence, determining the optimal concentration in this regard is very important because reduced growth and yield of different plants have been reported at high concentrations of SA [17].…”

Although the effects of salicylic acid (SA) on increasing plant growth in saline conditions have been well known, the mechanisms of induction of salinity tolerance, especially in quinoa (Chenopodium quinoa Willd.), are not fully understood. In the present work, two quinoa genotypes (Titicaca and Giza1) were treated with different SA concentrations (0, 0.75, and 1.5 mM) under varied irrigation water salinities (0, 7, 14, and 21 dS m−1). Salinity decreased shoot and root growth, potassium (K+) concentration, and potassium to sodium ratio (K/Na) and increased sodium (Na+) and chlorine (Cl−) concentrations in both cultivars. Calcium (Ca2+) and magnesium (Mg2+) concentrations increased in 7 dS m−1 but decreased in higher salinities. The growth and salinity tolerance of Giza1 were higher, while the growth of Giza1 increased and of Titicaca decreased in high salinity. Salicylic acid at 0.75-mM concentration increased shoot and root growth and improved the ions concentration in favor of the plant, while the 1.5-mM concentration either had no significant effect or had a negative impact. The ions distribution estimated by K/Na selectivity and storage factor (SF) indicated quinoa accumulated more ions in roots under saline conditions. Salicylic acid increased NaSF, ClSF, and MgSF and decreased KSF and CaSF, meaning less Na+, Cl−, and Mg2+ and more K+ and Ca2+ transferred to shoots in SA-treated plants. Importantly, Giza1, as the more tolerant cultivar, had higher NaSF and ClSF and lower KSF, CaSF, and MgSF. In general, the concentrations of ions in roots were higher than in shoots. The results indicated more ions accumulation in the root could be one of the most important mechanisms of salinity tolerance in quinoa, and the more tolerant cultivar (Giza1) transferred less Na+ and Cl− and more K+ and Ca2+ and Mg2+ to the shoot.

“…SA probably improves nutrients absorption under DS and salinity, which will increase the plant height and growth rate (Eraslan et al, 2007). These effects of SA may be due to the more significant role of SA in water storage in plant cells and the increase in enzymatic activity under stress conditions (Pirasteh-Anosheh et al, 2015), consequently increasing yield characters. The application of SA also changes the hormonal balance in the plant and increases auxin and cytokinin levels in non-stress conditions.…”

Salicylic acid (SA) increases crop's resistance against drought stress (DS). The present study reports the effect of SA foliar spray on yield and its components in foxtail millet Basten cultivar under drought stress conditions with three irrigation levels (45%, 65%, and 85% humidity of field capacity) as the main factor and four SA levels (0 to 2 mM) as the subplot. The results revealed that the freshest forage yield (36.76 ton.ha -1 ) and plant height (89.6 cm) is obtained from control and three mM SAFS treatments. The highest stem yield (6.971 ton/ha), leaf yield (4.947 ton/ha), grain yield (2.568 ton/ha), panicle length (18.7 cm), seed number per panicle (3670), 1000-seed weight (3.64 g) and a number of leaves per plant (11.43) were obtained by foliar spraying of 1.0 mM SA under normal conditions. Maximum harvest index (61.66%) was obtained under moderate stress conditions and 1.0 mM SA foliar spray. The highest levels of chlorophyll a, b, and total chlorophyll were 6.35, 4.02, and GUO et al. / Turk J Agric For 382 10.37 mg/WW, respectively, from the treatment without drought stress and the application of 1.0 mM SA. The results showed that spraying 1.0 and 3 mM SA under stress and normal conditions effectively yields and components in foxtail millet Basten cultivar in Sistan weather conditions.
