As biological growth regulator,fertilizer and prophylactic,arbuscular mycorrhizal fungi(AMF) were taken into account increasingly in continuable agriculture and natural zoology.AMF could not only significantly improve mineral absorption of tobacco,improve character of resistence to adversity and anti-disease and pest,and improved the micro-ecological environment in the soil of Flue-cured rhizosphere,but also increase the products and quality of tobacco.In the present paper,the resent advances in the research of tabacoo arbuscular mycorrhizas were briefly reviewed from there aspects:the resource of tobacco arbuscular mycorrhiza fungi,the main effect of arbuscular mycorrhizal on tobacco and the the main effect of arbuscular mycorrhizal fungi in the soil of tobacco.
