Experiments were performed to study effects of exogenous silicon (0, 2, and 8 mM) and pH stress (pH 3.0, 5.5, 8.0) on Festuca arundinacea. The effect on growth, photosynthetic pigments content and antioxidant enzymes activities were researched. Our results indicated that under pH 3.0 stress, above ground dry weight, the activities of catalase (CAT), peroxidase (POD) and chlorophyll content were maximum under the 2mM Si treatment and restrained under 8mM Si treatment. Under pH8.0 treatment, the plant height, the activities of APX, POD and chlorophyll content increased significantly with increase of the concentration of silicon treatment which were maximum under 8mM Si treatment, but the POD, dry weights of roots and above ground declined a little compared to 2mM Si treatment. It illustrates that under acid stress, the lower concentration of Si treatment is effective in alleviating the injury of plants under acid and alkali stress.
