[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.

CONCLUSION

The content of terpenoids in the aerial part of Isodon adenantha is positively correlated with AM fungi.
