PCoA plot of the relationship between samples on the basis of similarity in the community composition of bacterial OTUs. Two first components (PCoA 1 and PCoA 2) are plotted and represent 70.55% of the variation. SC, SQ, SX and SH represent bacterial communities from ‘Changguo Sang’, ‘Chuan Sang No.7637’, ‘Xin Lunjiao’, and ‘Hong Guo No.2’ in spring, respectively. AC, AQ, AX and AH represent bacterial communities from ‘Changguo Sang’, ‘Chuan Sang No.7637’, ‘Xin Lunjiao’, and ‘Hong Guo No.2’ in autumn, respectively.
