Abstract: Effects of different concentrations of eutrophic water on physio-ecological characteristics of Festuca arundinacea L. was investigated. The results showed that the diluted eutrophic water could significantly promote root growth of F.arundinacea. When diluted concentration was more than 50%, it inhibited plant height growth. Diluted concentration of the eutrophic waters had no significant effect on chlorophyll content, proline, soluble sugar, malondialdehyde (MDA) content, super-oxide dismutase (SOD) activity of F.arundinacea L.. The outer ring water could promote peroxidase (POD) activity, and 75% concentration could increase catalase (CAT) activity. From the analyses above, it could be concluded that irrigation with diluted eutrophic water would be feasible to F. arundinacea L., and quarters water was optimal for the irrigation.

Key words: eutrophic water, Festuca arundinacea L., antioxidase, proline, soluble sugar, MDA
