BAUTISTA, Juan Manuel et al. Colonization by mycorrhizae in the production of cranberry seedlings in nursery (Vaccinium spp.) cv Biloxi. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.3, pp.695-703. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v8i3.42.

In Mexico the cranberries production is currently expanding with the use of cv. Biloxi mainly although the production of new plants in nursery presents a poor quality of the propagated material. It is known that as Ericaceae, the Vaccinium genus has developed a co-evolution with mycorrhiza species, but the usefulness of these in propagation in nursery is not yet available to recommend an inoculation. This paper tested the colonization by EndosporR, a commercial mycorrhizal complex and the colonization by native mycorrhizae of Gaultheria sp. and V. confertum in seedlings of cv. Biloxi. The colonization only by Gaultheria sp. shows a positive effect on plant height, leaves number, frequency and intensity of root colonization. The commercial EndosporR product and mycorrhizae from V. confertum were not effective in the growth and colonization variables. The implications for the propagation and organic cultivation of cranberries in Mexico are discussed.
