Salicylic acid alleviates the cadmium toxicity in barley seedlings.
Salicylic acid (SA) plays a key role in plant disease resistance and hypersensitive cell death but is also implicated in hardening responses to abiotic stressors. Cadmium (Cd) exposure increased the free SA contents of barley (Hordeum vulgare) roots by a factor of about 2. Cultivation of dry barley caryopses presoaked in SA-containing solution for only 6 h or single transient addition of SA at ...
متن کاملSalicylic Acid Alleviates the Copper Toxicity in Zinnia elegans
Salicylic acid (SA) plays a key role in plant disease resistance and hyper-sensitive cell death but is also implicated in hardening responses to abiotic stress. The aim of this study is to examine the effects of salicylic acid on the growth, eco-physiological and biochemical characteristics in Zinnia elegans plant exposed to copper stress. Effects of copper (Cu) on biomass, root length and shoo...

متن کاملSalicylic Acid Protects Photosynthesis against Cadmium Toxicity in Pea Plants
In the present study we have investigated the possible mediatory role of salicylic acid (SA) in protecting photosynthesis against cadmium (Cd) toxicity. The exposure of pea plants to increasing Cd concentrations (0.5, 1.0, 2.0 and 5.0 µM) during early stages of their establishment caused a gradual decrease in shoot and root fresh weight accumulation, the rate of CO 2 fixation and the activity o...
متن کاملPretreatment with salicylic acid and nitric oxide alleviates silver nanoparticles toxicity in medicinal Hypericum perforatum plants
Since the use of seed priming agents to reduce the potential toxicity of AgNPs has not been explored, we evaluated the combined effects of 0.1 mM salicylic acid (SA) and 0.1 mM nitric oxide (NO) on responses of Hypericum perforatum plants to Ag-induced stress. The results of growth parameters together with measurement of malondialdehyde (MDA) revealed that exposure to AgNPs or AgNO3 caused more...
