Interaction effects of nitric oxideand salicylic acid in alleviating salt stress of Gossypium hirsutum L.

The effects of sodium nitroprusside (SNP, a nitric oxide donor), salicylic acid (SA), and their combination on some physiological parameters of cotton (Gossypium hirsutum L.) seedlings grown under saline conditions were studied. 100 mM NaCl resulted in a decrease in , and induced an increase in the...

However, the protective action of NO and SA (especially 0.05 mM SNP and 0.05 mM SA) against salt-induced oxidative damage was more efficient than the separate effects of SA and SNP.We observed that the accumulation of osmotic regulators was apparently accelerated by 0.05 mM SNP and 0.05 mM SA. As well, it was observed that they had synergistic effects in antioxidant system and ion absorption. Thus, the combination of SNP and SA can be a new indicator of a protective mechanism to lower lipid peroxidation, improve ion absorption, activate the metabolic of osmotic-regulated substances and facilitate membrane transport to detoxify reactive oxygen species (ROS).info:eu-repo/semantics/openAccessChilean Society of Soil Science / Sociedad Chilena de la Ciencia del SueloJournal of soil science and plant nutrition v.15 n.3 20152015-09-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-95162015000300002en10.4067/S0718-95162015005000024
