The protective action of salicylic acid (SA) pre-treatment on soybean plants before cadmium (Cd) addition was tested. Oxidative stress parameters, such as TBARS formation, glutathione and chlorophyll content, were altered by Cd, instead no differences were observed in plants only pre-treated with SA. Antioxidant enzymes were affected by Cd treatment, while(More)
The present study was undertaken to test the influence of exogenously applied jasmonic acid (JA) upon the oxidative stress exerted by Cd in soybean plants. It was found that depending on its concentration, JA can improve plant antioxidant responses against Cd. Pretreatment with 20 μM JA effectively ameliorated Cd-induced oxidative stress as indicated by the(More)
Plants are frequently subjected to different kinds of stress, such as salinity and, like other organisms, they have evolved strategies for preventing and repairing cellular damage caused by salt stress. Glycine max L. plants were subjected to different NaCl concentrations (0-200 mM) for 10 days. Treatments with 100 and 200 mM NaCl induced ion leakage and(More)
