摘要：

This experiment tested the impact of grass species and fungal endophyte status and strain on soil nitrification. Three C3 grass-endophyte combinations were tested: Festuca arundinacea-Neotyphodium coenophialum; F. pratensis-N. uncinatum; Lolium perenne-N. lolii, and included different strains of endophyte and endophyte-free grasses. Three C4 species- Brachiaria decumbens, Paspalum dilatatum and Pennisetum clandestinum-of unknown Acremonium endophyte status, were also tested. Plants were grown for 6 weeks without fertiliser in pots in a field soil (Mollic Psammaquent), then rhizosphere soil was sampled and incubated at 27 degrees C with and without (NH4)(2)SO4. The NO3--N production was measured weekly. The presence of plants significantly increased the nitrification rate compared with bare soil. There were significant differences (P = 0.02) among plant species. In all cases, endophyte presence increased nitrification in soil samples (P < 0.001) relative to endophyte-free within a species.
