Appendix K. Ordination diagram (sample plot) of principal components analysis (PCA) on (A) bacterial and (B) fungal denaturing gradient gel electrophoresis (DGGE) profiles of Poa annua rhizosphere samples.
|FIG. K1. Ordination diagram (sample plot) of PCA on (A) bacterial and (B) fungal DGGE profiles of P. annua rhizosphere samples. Scores are shown for inoculum treatments (origin: = A. geniculatus, = A. spica-venti, = P. annua, = C. canadensis, = C. bursa-pastoris, = V. arvensis) and for the sterilized control treatment (). Each point represents one sample. Eigenvalues along the axes indicate the amount of explained variability in species composition.|
