In addition to drought and low mineral content, salinity is one of the most prolonged and unfavorable conditions that has a negative effect on plant health. Significantly, not all plants react in a similar manner to those compounds (lethal osmotic constituents) due to the existence of an array of resistance mechanisms that assist the plant to overcome the stress. These adaptive mechanisms might consist of accumulation of organic components, and the regulation of antioxidant machinery (van Zelm et al. 2020). It has been detected that rice plants exposed to SNP (NO donor) had improved overall growth. This shielding influence exerted by exogenous application of NO was related to the preservation of high relative moisture content and chlorophyll, whereas ionic discharge was sustained at a low level. Likewise, a clear effect on the accumulation of Na⁺ and K⁺ was also witnessed. These results proposed that NO has a protective effect on plants including managing water levels, sustaining ionic balance, and minimizing the damage imposed during early stages of the salinity response (Suzuki et al. 2014; Bashir et al. 2019; Hernández 2019).
