Study on the adaptability of Festuca festina and F. arundinacea in hot and dry summer in Chongqing

Festuca festina and F. arundinacea were used to test their adaptability under high temperature and drought stress for 8 days in Chongqing. The result indicated that the response of F. arundinacea to the stress was more sensitive because of its obvious damaged symptoms. Along with the stress, the chlorophyll content rapidly reduced, the malondialdehyde content increased and the soluble sugar accumulation was relatively slow for F. arundinacea. It could be concluded that F. festina was better than F. arundinacea for hot and drought resistance in summer.
