Abstract
The present invention relates to a method of producing mycorrhizal fungal propagules in vitro in a two-compartment container having a gellified medium, which comprises the steps of: a) cultivating aseptically transformed dicotyledon root organs, capable of autonomous growth in vitro, in a first compartment containing a mineral minimal medium with sugar, wherein the medium is suitable for root growth; b) inoculating the transformed root organs with endomycorrhizal spores; and c) cultivating the inoculated transformed root organs for a time sufficient for the mycorrhizal fungi to transfer to a second root-free and root exudate-free compartment containing the mineral minimal medium of step a) and for the mass production of fungal propagules to occur in the second compartment.
