The effects of arbuscular mycorrhizal (AM) fungus, Glomus mosseae, on growth, osmotic adjustment and antioxidant enzymes of bahia grass (Paspalum notatum) were studied in potted plants under water stress conditions. AM colonization significantly enhanced the plant height, root and shoot fresh weight, Phosphorus (P), potasium (K), manganese (Mn) contents in shoots, P, calcium (Ca), Mn contents in roots, whereas obviously decreased zinc (Zn) content in shoots, iron (Fe), boron (B), copper (Cu) contents in roots. During water stress, the relative water and chlorophyll contents were relatively stable and signifciantly higher in AM than in non-AM plants, AM inoculation notabley decreased the shoot relative conductivity and malondialdehyde (MDA) content, markedly increased shoot peroxidase (POD) activity and proline content, while AM infection did not affect the dismutase (SOD) activity of shoots. Our results suggested that AM colonization improved the protective enzyme activity (such as POD) and osmotic adjustment originating from proline P, K, Ca, resulting in the enhancement of drought tolerance.
