Effects of Exogenous Nitric Oxide on Mineral Nutrition and Some Physiological Parameters of Maize Grown under Salinity Stress
Abstract
: In the present study, the effect of nitric oxide (NO) on growth, mineral nutrients
concentrations and some physiological properties of maize under salt stress condition was
investigated. For this propose, 40 mM NaCl (except control), exogenously applied sodium
nitroprusside (SNP) as a NO donor, and methylene blue (MB), as a NO scavenger, (0, 0.5 and 1.0
mM) were supplied.
Results of this study showed that, NaCl and SNP applications were significantly decreased when
plant fresh and dry weight compared to control. Membrane permeability, lipid peroxidation, measured
in terms of malondialdehyde (MDA) content, excised-leaf water loss, and relative water content,
stomatal resistance and proline accumulation were not affected by NaCl and SNP treatments.
Nitrogen, P, Cl, Na, Mg, Fe, Zn, Cu and Mn concentrations of maize plant were significantly affected,
however no significant effect on the K and Ca concentrations of maize plant was observed. Nitrogen,
Na, Cl, Na, K, Ca, Mg, Fe, Zn and Mn concentrations were increased by increasing levels of SNP.
The results of this study indicated that high doses (0.5 mM and 1.0 mM) of exogenously applied
sodium nitroprusside (SNP), as a NO donor, had not positive effect to improve plant performance
against salinity stress.
