“…When seedlings are under stress, the products can act as attenuators, enabling the establishment of seedlings (Khan et al, 2015). This was evidenced by analyzing studies carried out with initial treatment of Medicago sativa L. seeds with gibberellic acid, which reduced the negative effect of salts on seedling growth (Younesi & Moradi, 2014). Moreover, reuse water, such as fish farming wastewater, has high conductivity, but with elements that are not always harmful.…”

Pumpkin (Curcubita moschata Duchesne) production in quantity and quality is often restricted due to adverse environmental conditions. Thus, the objective was to evaluate the action of phytohormones as stress attenuators on the germination and initial growth of pumpkin seedlings, cv. Sergipana, under different types of water. The design adopted was completely randomized, in a 3 × 4 factorial scheme, with four repetitions. In addition to the control, the seeds were treated with the gibberellic and salicylic acids and irrigated with the supply water, fish farming wastewater, artesian well water and solution of the mixture of fish farming wastewater + artesian well water, in a 1:1 ratio. The variables evaluated were germination, first germination count, germination speed index, length of shoots and roots, dry mass of shoots and roots, soluble sugars, amino acids and proline. Treatment of pumpkin seeds, cv. Sergipana, with gibberellic and salicylic acids improved germination kinetics and attenuated the effects of water salinity during the initial growth of pumpkin seedlings.

“…Harris et al [131] reported that seed priming with ZnSO 4 enhance grain yield in chickpea. It has been observed that priming with Gibberellins can enhance seed germination and improve salt tolerance of alfalfa by improving antioxidant activities and reducing membrane damage [132]. Azooz [133] observed that priming with salicylic acid enhance salinity tolerance in two faba bean genotypes.…”

Salinity is an ever-present major constraint and a major threat to legume crops, particularly in areas with irrigated agriculture. Legumes demonstrate high sensitivity, especially during vegetative and reproductive phases. This review gives an overview of legumes sensitivity to salt stress (SS) and mechanisms to cope with salinity stress under unfavorable conditions. It also focuses on the promising management approaches, i.e., agronomic practices, breeding approaches, and genome editing techniques to improve performance of legumes under SS. Now, the onus is on researchers to comprehend the plants physiological and molecular mechanisms, in addition to various responses as part of their stress tolerance strategy. Due to their ability to fix biological nitrogen, high protein contents, dietary fiber, and essential mineral contents, legumes have become a fascinating group of plants. There is an immense need to develop SS tolerant legume varieties to meet growing demand of protein worldwide. This review covering crucial areas ranging from effects, mechanisms, and management strategies, may elucidate further the ways to develop SS-tolerant varieties and to produce legume crops in unfavorable environments.

“…These results reflect that after priming seeds with comprehensive agents, soybean seedlings strengthen the ability of eliminating ROS through enhancing activities of the antioxidant enzyme system. Younesi and Moradi (2015) also proved that there is a negative relationship between antioxidant enzyme activity and MDA.…”

“…Gibberellins can inhibit abscisic acid (ABA) activity by activating the ABA-catabolizing enzymes and decreasing ABA accumulation during germination and then enhance seed germination (Miransari and Smith, 2014). GA 3 priming can improve seed germination and increase salt tolerance of alfalfa through enhancing the activities of antioxidant enzymes and reducing membrane damage as estimated using a reduction of electrolyte leakage and MDA level in salt stressed seedlings (Younesi and Moradi, 2015).…”

Soda saline-alkali soil has double adverse effects on growth, morphogenesis and yield of the crops by creating a salinity stress and a high pH value in the rhizosphere surroundings of the plant. Seed priming can be an effective approach to enhance stress adaptation in seedlings growing in salinity stressed conditions. The present study examined the role of hydropriming and comprehensive seed priming with ZnSO 4 , CaCl 2 , betaine hydrochloride and GA 3 to enhance the soda saline-alkali tolerance in soybeans (Glycine max [L.] Merr.) seedlings. An unprimed control treatment was also maintained for comparison. The results show that two seed priming treatments can effectively mitigate the negative effects of soda salinealkali stress. Nevertheless, compared with hydropriming, soybean seedlings from the comprehensive seed priming treatment had better growth performance through accumulation of soluble sugar and free proline contents, enhancing the activities of superoxide dismutase (SOD) and catalase (CAT), decreasing the malondialdehyde (MDA) content formed from lipid peroxidation, increasing the photosynthetic pigment contents, maintaining a better membrane integrity of the chloroplasts and mitochondria, and generating more starch grains in the chloroplasts of spongy mesophyll cells under soda saline-alkali stress. In conclusion, our results suggest that soybean seedlings from comprehensive seed priming exhibited a higher tolerance to soda saline-alkali stress than the unprimed control treatment.
