Abstract:
Taking perennial ryegrass ‘Aishente No2’ seed as material，using constant temperature incubator,the effects of super absorbent polymer(SAP) on heat resistance character and the physical indicators：relative electrical conductivity,root activity,proline (Pro),malonaldehyde (MDA),superoxide dismutase (SOD),catalase (CAT),and so on were studied.The results showed that with the increasing of high temperature stress,SOD,CAT activity and root activity were decreased,the content of Pro,MDA and relative electrical conductivity were increased.With the SAP,the heat resistance character of turfgrass was higher than those in control.But under the same stress temperature and time,without SAP as control,SOD and CAT activity,Pro content and root activity were significantly increased,MDA content and electrical conductivity were significantly decreased.
