| Abstract/Contents: | "Physiological characteristics of salt tolerance in centipedegrass (Eremochloa ophiuroides (Munro) Hack.) were investigated by comparing ion uptake, osmotic regulation, osmolytes, oxidative stress and antioxidant enzymes of salt-tolerant cultivar 'TifBlair' and salt-sensitive 'Common'. Treatments at 0-150 mmol L-1 NaCl were conducted for 10 days. Growth was higher in 'TifBlair' than in 'Common' at 25 and 50 mmol L-1 NaCl, and was depressed in both cultivars at above 75 mmol L-1 NaCl. No significant difference in Na and Cl concentrations in the shoot and roots was observed between the cultivars, although 'TifBlair' was more tolerant to Na and Cl than 'Common'. Osmotic pressure, glycinebetaine and free proline concentrations in the shoot increased in both cultivars with an increase in NaCl concentration; the increase was higher in 'TifBlair'. Malondialdehyde concentration, an index of oxidative damage, in the shoot increased in both cultivars with an increase in NaCl concentration; the increase was not significantly different between the cultivars. On the contrary, hydrogen peroxide concentration was higher in 'TifBlair' than in 'Common'. ATPase activity of the shoot plasmalemma increased in 'TifBlair' with an increase in NaCl concentration, while decreased in 'Common' at 50 mmol L-1 NaCl. The activity of antioxidant enzymes (superoxide dismutase, peroxidase, catalase and ascorbate peroxidase) tended to be higher in 'TifBlair' than in 'Common'. The results suggest that adjustment of osmotic pressure by accumulation of compatible solutes and exclusion of Na and Cl, and elimination of activated oxygen by induction of antioxidant enzymes are responsible for the salt tolerance of centipedegrass 'TifBlair'." |
