Effect Of Exogenously Applied Salicylic Acid On Cadmium Chloride-Induced Oxidative Stress And Nitrogen Metabolism In Tomato (Lycopersicon Esculentum L.), Esra Koç, Ayşen Sülün Üstün, Nuri̇ Çeli̇k
Turkish Journal of Biology
Salicylic acid (SA) has a key role in the formation of induced systemic resistance and hypersensitive cells, but it has also been indicated to be effective in the formation of strong responses against abiotic stresses such as drought, cold, heavy metal toxicity, and osmotic stress. This study has demonstrated a connection between the total soluble protein and the nitrate reductase (NR) activity. In 20 \muM CdCl_2, 40 \muM CdCl_2 + 0.5 mM SA, and 100 \muM CdCl_2 + 0.5 mM SA treatments, on the 1st day following the treatment an increase was detected in the NR activity when compared to …

The effects of salicylic acid (SA) on leaf rolling under osmotic stress in Ctenanthe setosa (Roscoe) Eichler were evaluated. The leaves were pretreated with SA, paclobutrazol (PAC), and antioxidant enzyme inhibitors for 15 h and then kept in polyethylene glycol (PEG) for 4 h to promote osmotic stress. The degree of leaf rolling was measured every hour during the 4-h PEG treatment. Antioxidant enzymes (superoxide dismutase, catalase, ascorbate peroxidase, and guaiacol peroxidase) and NADPH oxidase (NOX) activities, endogenous SA contents, hydrogen peroxide, proline, and soluble sugar were determined immediately after PEG treatment. SA treatment retarded leaf rolling and induced antioxidant …
