Effect of interaction between salinity and nanoparticles (Fe2O3 and ZnO) on physiological parameters of Zea mays L

A pot experiment was conducted to evaluate the effects of zinc oxide (ZnO) and iron oxide (Fe 2 O 3 ) nanoparticles on the growth of two maize cultivars under the saline condition. Salt stress induced decreases of shoot, root dry weight, leaf area and leaf gas exchange of S.C. 704 more than Bulk. Th...

Description
Summary:A pot experiment was conducted to evaluate the effects of zinc oxide (ZnO) and iron oxide (Fe 2 O 3 ) nanoparticles on the growth of two maize cultivars under the saline condition. Salt stress induced decreases of shoot, root dry weight, leaf area and leaf gas exchange of S.C. 704 more than Bulk. The increase of salinity level, chlorophyll a, b and total chlorophyll content and iron (Fe) and zinc (Zn) concentrations under all spray treatments declined. Application of ZnO and Fe 2 O 3 significantly enhanced the root growth (17%), net carbon dioxide (CO 2 ), assimilation rate (8%) and sub-stomatal CO 2 concentration (5%) of maize compared to control. Nanoparticles of Fe 2 O 3 and ZnO caused an increase in leaf Fe (22%) and Zn (11%) concentrations, respectively, compared with normal forms. According to the results, although the alleviation effects of Zn and Fe have been demonstrated under stress conditions, nanoparticles were more effective than normal forms, which may be due to their shape, size, distribution and characteristics.
