ABSTRACT
The increased salinity in greenhouses has become a problem of great concern. In this study, it was observed that the salt-induced oxidative damages (indicated by MDA, H2O2 and antioxidant enzymes, including POD, SOD and CAT) could be alleviated by application of NO gas. Consequently, although both photosynthesis and growth in plants were inhibited by NaCl stress, they were restored by NO gas application, and the fresh and dry biomasses of edible parts increased by 60% and 27% over NaCl stress treatment, respectively. Furthermore, gaseous NO application also significantly elevated the levels of several antioxidation-associated compounds such as proline, ascorbate, glutathione, total phenolics and flavonoids, as well as the total antioxidant capacity (indicated by DPPH scavenging activity) in NaCl-treated plants. Keeping in mind all of the above, we concluded that atmospheric application of trace amounts of nitric oxide gas could be an effective strategy for improving both biomass production and nutrition quality in spinach under salt stress.
