Figure 3.
Principal component analysis (PCoA) of bacterial communities as affected by (A) Treatment of streptomycin or water, (B) soil pH, and (C) soil site orchard. Plots are based on Bray-Curtis dissimilarities comparing bacterial communities according to treatment, soil pH or orchard. P-values were calculated using PERMANOVA. (A) Circle, treated with streptomycin; square, treated with water; (B) circle, low pH; square, neutral pH; (C) triangle, Güttingen orchard; circle, Wädenswil orchard; square, Lindau orchard.
