[Effects of arbuscular mycorrhizal fungi on terpenoids in Isodon adenantha].

Objective: To observe the effects of Arbuscular Mycorrhizal (AM) fungi on terpenoids in Isodon adenantha.

Methods: Three different treated plant groups were divided as followings: indoor inoculation with AM fungi, non-inoculation with AM fungi, and outdoor natural growth, the effects of AM fungi on the major terpenoids in Isodon adenantha were evaluated.

Results: AM fungi had little influence on the content of terpenoids in underground part of Isodon adenantha, but they showed great impact on the content of terpenoids in the aerial part of the plant.
