Mycorrhiza is a obligate symbionts so it can not grow without root. I found it in many research article.
I doubt , since mass multiplication of VAM is host roots specific ...
@ Bindu, AM fungi is a obligate symbiont therefore it so far can not grow in the synthetic medium. But the germination process can be studied on suitable media. Also the infection process can be followed on these media with transformed root cultures . Otherwise you may try with put some soil in the common fungal media.
Obviously it can.
You cannot grow it to thriving conditions though.
But can culture them enough to cause root integration, when used on roots.
SOO many companies are already doing this.
J. C. Tarafdar is correct. The spore germination is possible for some AMF species using specific culture media... but their whole life cycle is not possible yet.
These fungi have a low, or negligible, saprophytic ability and can apparently produce viable propagules only upon the biotrophic colonization of a susceptible host root. They are thus considered physiologically obligate symbionts and the related literature reflects the failure to grow them on synthetic media. But the germination process can be studied on suitable media. Also the infection process can be followed on these media with transformed root cultures.
