Effects of ZnO NPs on phenolic compounds of rapeseed seeds under salinity stress
تنش شوري
Salt Stress
پژوهشي
Research
<strong>In this study, rapeseed Okapi cultivar was treated under three NaCl levels (0, 50 and 100 mM) and four Zinc oxide nanoparticles (ZnO NPs) concentrations (0, 20, 40 and 80 mgL<sup>-1</sup>) at flowering stage. The experiment was performed in</strong><strong> a completely randomized design (CRD) in </strong><strong>the greenhouse</strong><strong> of Biology Department of Urmia University, in 2015</strong><strong>. Results showed that </strong><strong>NaCl (100 mM) </strong><strong>significantly enhanced </strong><strong>total phenolic, flavonoids, </strong><strong>anthocyanin and phosphorus contents </strong><strong>and increased </strong><strong>ability to scavenge the DPPH radical scavenging activity. Treatment with ZnO NPs (80 mgL<sup>-1</sup>) significantly elevated total phenolic and decreased anthocyanin, phosphorus and zinc contents and seed weight</strong><strong>. Foliar application of ZnO NPs ameliorated the negative impacts of NaCl by reduction in phenolic, anthocyanin and phosphorus contents and elevation in seed oil content (20.82%) and seed weight (79.28%) at 50 mM salinity and 20 mgL<sup>-1</sup> of ZnO NPs compared to</strong><strong> NaCl (50 mM) alone</strong><strong>. </strong><strong>In conclusion, foliar application of </strong><strong>ZnO NPs at 20 mgL<sup>-1</sup></strong> <strong>is recommended to farmers as replacement for fertilizers to</strong><strong> alleviate the adverse effects of salinity stress.</strong>
