Abstract/Contents:"A pot trial with warm-season turfgrass Zoysia matrella was conducted in Nanjing, Jiangsu, China in 2007 and its leaves were sprayed with 10 mmol H2O2/litre and distilled water (as the control) to investigate effects of exogenous H2O2 on chilling tolerance. The pretreated plants were first cultured at 32/26°C (day/night) for 12 hours and then at 7/2°C (day/night) for 0, 3 and 6 days. It is found the exogenous H2O2significantly increased the activities of catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and glutathione-S-transferase (GST) in leaves to reduce oxidative harm by chilling. The H2O2 possibly played a role of signalling molecule protecting leaves against subsequent chilling-induced damage. During the chilling, the contents of malondiadehyde and hydrogen proxide in the leaves were decreased and the activities of CAT, peroxidase, APX, glutathione reductase and glutathione-dependent peroxidases were increased under H2O2 pre-treatment, suggesting that the chilling tolerance of plants was improved. The total content of glutathione in the leaves were not changed, however, oxidized glutathione:reductive glutathione (GSSG:GSH) ratio were decreased under H2O2 pre-treatment before chilling treatment and continuously decreased with chilling time, which indicated that the GSSG:GSH ratio possibly involved in the signal transduction of chilling."
