We conducted a study of the effect of super absorbent polymer (SAP) on the seed germination and physiological characteristics of Festuca arundinacea. Two different water and five aquasorb treatments were investigated based on a pot experiment. Comprehensive evaluation combining with 9 indicators subordinate function showed the Festuca arundinacea drought resistance ability. The results showed that: (1) SAP may effectively enhance the germination percentage and germinating potential of Festuca arundinacea. Compared with the control, the optimum SAP of sufficient amount of water conditions is 0.10%, they were improved by 4.97% and 6.05%, the condition of limited water supply was 0.40%, they were improved by 38.13% and 45.91%; (2) SAP may effectively enhance the chlorophyll content and decreased SOD, POD, MDA contents of the seedling leaves of Festuca arundinacea, the physiological index showed that change range was smaller when the concentrations of SAP ranged from 0.20% to 0.40%; (3) the application of SAP could improved the root vitality; (4) through the subordinate function analysis, under sufficient amount of water conditions, drought resistance of the five kinds of concentrations of SAP decreased in the order: 0.20% > 0.30% > 0.10% > 0.40% > 0.00%, on the contrary, the consequence was 0.30% > 0.40% > 0.10% > 0.20% > 0.00%. Therefore, applying 0.20% or 0.30% of SAP can increase the Festuca arundinacea seed germination of subordinate function, and it can be used in planting, maintenance and water-saving of urban green space.
