Effect of VAM fungi on phosphatase activity in maize rhizosphere

Abstract

Abstract: The effect of VAM fungi on phosphatase activity in maize rhizosphere was examined by pot culture experiment,in which,three-compartment-pots were used,the central compartment being separated from the outer two by a nylon net with 30μm mesh.Plants were harvested 70 days after planting.Soil acid and alkaline phosphatase were measured at different distances from root surface.The results showed that VAM increased the activities of soil acid and alkaline phosphatase in the rhizosphere.It was found that different phosphorous sources had different effects on phosphatase activity.

Key words: Vesicular-arbuscular mycorrhizal, Maize, Acid phosphatase, Alkaline phosphatase
