Arbuscular mycorrhiza symbiosis of Dactylis glomerata L.and Anthoxanthum odoratum L . in an Acidic pasture
D.glomerata is the main grass on artificial pastures in the north region of Japan.In recent years, most of those pastures have problems with weeds that decrease the growth, productivity and quality of the grasses.Among the weeds, A.Odoratum is the most widespread weed in the region that is dominated by acid soils.However, the mechanism of dispersion of this weed is not known.Many studies showed that clear beneficial effect of arbuscular mycorrhiza on grass tolerance to Al toxicity and soil acidity ( Cuenca and Meneses 2001).Therefore we propose that mycorrhizal symbiosis of both plants may explain their relative success in the field.In this study, we investigated the arbuscular mycorrhizal symbiosis of D.glomerata and A.odoratum in a strongly acidic artificial pasture.
