Abstract/Contents:"Warm-season turfgrass Manilagrass (Zoysia matrella) was pretreated with 10mmol/L H2O2 in pot experiments, and the effect of exogenous H2O2 on chilling-tolerance were studied. The results showed that exogenous H2O2 significantly increased CAT, APX, GPX and glutathione-S-transferase (GST) activities in manilagrass to reduce the oxidative harm by chilling. H2O2 possibly played a role of signaling molecule protecting them against the subsequent chilling-induced damage. During the chilling, content of malondialdehyde (MDA) and hydrogen proxide (H2O2) were decreased and activities of catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX), glutathione reductase (GR) and glutathione-dependent peroxidases (GPX) were increased under H2O2 pretreatment, suggesting the improvement of chilling tolerance. The total content of glutathione were not changed, however, oxidized glutathione/reductive glutathione (GSSG/GSH) ratio were decreased under H2O2 pretreatment before chilling treatment and continuously decreased with chilling treatment, which implied that the GSSG/GSH ratio was possibly involved in signal transduction of chilling."
