“…The activity of antioxidant enzymes (pyrogallol peroxidase, ascorbate peroxidase, and polyphenol oxidase) was determined by the procedure described in Chen and Asada [ 27 ] and Sheyhakinia et al [ 28 ]. Free proline was extracted from fresh pearl millet leaves (0.1 g) by 3% sulfosalicylic acid [ 29 ]. Soluble carbohydrates were extracted with ethanol (80%) and then measured by the anthrone reagent method [ 30 ].…”

Shrimp waste is rich in organic compounds and essential plant nutrients, e.g., calcium (Ca), and converting these wastes to organic fertilizer is important for environmental preservation and to achieve sustainable agricultural management. In the current study, Ca-rich biochar was prepared from shrimp wastes (SWB) by pyrolysis at 300 °C. We hypothesized that the Ca-rich biochar will help in solving the problem of plant growth in saline soil by reducing sodium (Na) uptake and mitigating oxidative stress. The current study aimed to investigate the effect of SWB on the quality of saline sandy soil and the mechanism of salt resistance in pearl millet (Pennisetum glaucum L.). Pearl millet plants were planted in saline sandy soil (10 dS m−1) in wooden boxes (1.3 × 0.8 m size and 0.4 m height), and 5 doses (0, 1.0, 1.5, 2.0, and 2.5% (w/w)) of SWB were added. SWB application increased the soil quality and nutrient uptake by pearl millet plants. The highest rate of SWB increased the soil microbial biomass carbon and the activity of dehydrogenase enzyme by 43 and 47% compared to the control soil. SWB application reduced the uptake of sodium (Na+) and chloride (Cl−) and increased the K/Na ratio in the leaf tissues. SWB addition significantly increased the activity of antioxidant enzymes, e.g., ascorbate peroxidase (APX), polyphenol oxidase (PPO), and pyrogallol peroxidases (PPX). The application of 2.5% SWB to the saline soil increased the soluble carbohydrates and proline in plant leaves by 75 and 60%, respectively, and reduced the malondialdehyde (MDA) by 32% compared to the control. SWB enhanced the antioxidant defense and mitigated oxidative stress by improving the synthesis of osmoprotectants, e.g., soluble carbohydrates and proline. Sandy saline soils in arid and semiarid areas suffer greatly from low organic matter contents, which reduces the soil quality and increases the risk of salt during plant growth. The high organic matter and calcium content (30%) in the shrimp waste-derived biochar improved the quality of the saline sandy soil, reduced the uptake of toxic salts, and increased the quality of the forage material. The addition of recycled shrimp waste to saline low-fertility soils improves soil productivity and is safe for soil health.

This study was performed to appraise the effects of several seed pretreatment solutions and priming time on seed germination indices and growth characteristics of Hibiscus sabdariffa L. in various salt stress levels. Seed priming was accomplished by KCl (1 and 2 %), Na2SO3 (0.5 and 1 %), KNO3 (0.5 and 1 %), and Ca2CO3 (1 and 2 %) as halopriming and distilled water as hydropriming at 12 and 24 h priming durations and control (non-primed), then primed seeds exposed to four levels (0, 50, 100, 200 mM) of NaCl solutions. The highest germination percentage was observed in 12 and 24 h hydropriming (63.3 and 53.3 %) and non-primed (56.6 %) under normal condition, respectively. Besides, there was no germinated seed at 24 h priming by 0.5 and 1 percentage of KNO3. Under saline condition, 24 h 2 % Ca2CO3 had the highest germination percentage (43.3 %) in 50 mM, while 12 h treatment with 0.5 % Na2SO3 (33.3 %) had high germination percentage in 100 mM levels of saline conditions. Also, the highest germination rate index was observed in 0.5 % Na2SO3 with 12 h treatment time (4.05 and 3.95 respectively) in 50 and 100 mM levels of saline conditions. Overall, salt stress considerably reduced germination and growth traits of Hibiscus sabdariffa L. seedlings. Considering the effect of various seeds priming of Hibiscus sabdariffa L. on germination indices like germination percentage and mean germination time, the importance of priming duration and type of priming solutions could be concluded.

“…In roselle ( Hibiscus sabdariffa ), the exogenous JA treatment protected roselle seedlings against salt-induced harms through enhancing the activities of both enzymatic and non-enzymatic antioxidants, such as APX, pyrogallol peroxidase (PPX), and PPO, and the accumulation of metabolites non-reducing sugars, total phenols, anthocyanins, flavonoids, and proline. The JA-treated roselle exhibited a significant increase in growth parameters under salt conditions compared to the WT [ 191 ]. In forage sorghum ( Sorghum bicolor ), at a high salinity level (200 mM), seeds treated with 10 mM JA showed a positive effect on various growth and physiological parameters such as emergence percentage, emergence rate, shoot length, total fresh weight, salt tolerance index, and total chlorophyll among others [ 192 ].…”

Soil salinity is one of the most limiting stresses for crop productivity and quality worldwide. In this sense, jasmonates (JAs) have emerged as phytohormones that play essential roles in mediating plant response to abiotic stresses, including salt stress. Here, we reviewed the mechanisms underlying the activation and response of the JA-biosynthesis and JA-signaling pathways under saline conditions in Arabidopsis and several crops. In this sense, molecular components of JA-signaling such as MYC2 transcription factor and JASMONATE ZIM-DOMAIN (JAZ) repressors are key players for the JA-associated response. Moreover, we review the antagonist and synergistic effects between JA and other hormones such as abscisic acid (ABA). From an applied point of view, several reports have shown that exogenous JA applications increase the antioxidant response in plants to alleviate salt stress. Finally, we discuss the latest advances in genomic techniques for the improvement of crop tolerance to salt stress with a focus on jasmonates.
