Effect of cinnamic acid on soil microbial characteristics in the cucumber rhizosphere
چکیده انگلیسی

In order to elucidate the effect of allelochemicals on soil microbial characteristics in the cucumber rhizosphere, the soil microbial biomass and respiration, community functional diversity and RAPD marker diversity as affected by exogenous cinnamic acid were studied. Exogenous cinnamic acid increased soil microbial respiration and the metabolic quotient, but decreased soil microbial biomass-C. Soil microbial community functional diversity and genetic diversity (as indicated by RAPD markers) were also significantly altered by exogenous cinnamic acid. These results suggest that allelochemicals can change soil microbial genetic diversity, biological activity and microbial metabolic activity, which alter soil microbial ecology and accordingly affect the growth of cucumber with accumulation in the soil of allelochemicals.
