Study on AMF in rhizosphere of Vetiver grass in field nursery

摘要

Vetiver grass was widely used and even named as the pioneer plant to control soil erosion, stabilize the slope and rehabilitate the ecology in South China,because of its high root tensile resistance and deep penetration.In the application of the vetiver grass, we recently find that it could not only tolerate water submersion and wet condition but also endure a certain degree of drought ; meanwhile it could absorb heavy metal so as to reduce the heavy pollution in soil to some extent.In order to explore the internal mechanism of these good characters of the vetiver grass and find out more plants with the ability to resist stress, we made the sample examination on arbuscular mycorrhizal fungus ( AMF) in rhizosphere of vetiver grass to make a further study of its biological function in the restoration from the soil degradation and the dependent relationship with plants.
