| Abstract/Contents: | "Exogenous salicylic acid (SA) has been documented to improve plant tolerance to various abiotic and biotic stresses. The potential impact of SA on improving bermudagrass freezing tolerance is unknown. This study was conducted to investigate the influence of SA application on bermudagrass freezing tolerance. Plugs (15 cm dia.) of mature 'Riviera' bermudagrass were taken from the field, transplanted into pots and grown for six months in a greenhouse. Salicylic acid was applied at concentrations of 0, 0.1, 0.5, and 1.0 mM to the foliage. A randomized complete block design was used with four replications. Leaf samples were collected at 0, 4, 8, and 12 days after treatment (DAT). At experiment termination, stolons were collected and subjected to a freezing test. Activities of antioxidant enzymes, abscisic acid (ABA) content, and stolon electrolyte leakage were determined. Salicylic acid treatment at 0.5 and 1 mM increased protein content, superoxide dismutase, ascorbate peroxidase, and guaiacol peroxidase activities, especially 8 days after treatment. Exogenous SA treatment also increased ABA content. The SA treatment at 0.1 and 0.5 mM inhibited catalase activity as measured at 4 and 8 days after application. Stolon electrolyte leakage, an indicator of freezing tolerance, was reduced by application of SA at 0.5 and 1.0 mM. The data suggest that SA application at 0.5 to 1.0 mM may induce defense-protection responses of bermudagrass, improving low temperature stress tolerance." |
