Figure 3. Canonical correspondence analysis (CCA) of the different AMF sequence types and soil properties detected in the three soils studied.

The eigenvalues of the first and second axes in the two-dimensional ordination diagrams are as follows: CCA1: 0.59 and CCA2: 0.55. C: native vegetation soil, R: Ricinus communis soil, J: Jatropa curcas soil, MBC:.microbial biomass C, CRL: colonized root length, AS: aggregate stability, OC: organic C, N: total N, EC: electrical conductivity.
