Abstract:
Taking three warmseason turfgrasses varieties（Zoysia matrella (L.) Merr.,Zoysia japonica Steud. ‘Songnan’,Cynodon dactylon×Cynodon transvadlensis ‘Tifdwarf’）as materials ,growth states of light tramp(LT),medium tramp(MT) and heavy tramp(HT) on three kinds of turfgrass were observed.Activities of catalase (CAT),superoxide dismutase (SOD) and peroxidase (POD) enzymes in the leaves were measured to evaluate the tramp stress resistance.The results showed that turf height,leaf width decreased dramatically under trample stress; With the increase of tramp intensity，the activities of CAT and SOD had no significant difference between，the activities of POD were decreased significantly (P<0.05); With the increase of tramp intensity，the activities of CAT and SOD were decreased，the activities of POD were increased significantly (P<0.05).The tramp stress resistant of zoysia matrella(L.) Merr. and zoysia japorica stead.‘Songnan’ were generally higher than of cynodon dactylon x cynodon transvaclcensis ‘Tifdwarf’ on the setting intensity.
