through R-R-MV rotation. The analysis of 16S rDNA clone
libraries showed that the Shannon –Weaver diversity index of
endophytic bacteria in R-R-MV approximates that in R-R-WF
rotation, whereas the richness indexes of Chao 1 and ACE in
R-R-MV rotation system were significantly higher than those
in R-R-WF rotation. The diversity of endophytic bacteria was
richer in R-R-MV. Both the culture-dependent and the culture-independent method revealed significant effect of long-term
different tillage systems on the microbial community.
