The symbiotic association of the mycelium of a fungus with the roots of a plant, as is found in the majority of vascular plants.

[myco- + Greek rhiza, root; see wrād- in Indo-European roots.]

(ˌmaɪ kəˈraɪ zə)

n., pl. -zae (-zē), -zas.
a symbiotic association of the mycelium of a fungus, esp. a basidiomycete, with the roots of certain plants, in which the hyphae form a closely woven mass around the rootlets or penetrate the cells of the root.

The presence of the disease-causing agent caused a fall of biomass of 82.5% with a death rate of 100% (table 1) whereas the presence of mycorhizae causes a drop in this rate mortality to 55%.
The compost as substrate (Ct) supports the growth of the seedlings well but does not seem to improve it by comparing it with the peat (Tt) (figures 1 and 3) and the presence of mycorhizae does not have either an effect (Cm).
