[Density and activity of microorganisms of the carbon cycle under the canopy of Myrica gale L].

Plants, especially actinorhizal, regulate edaphic microflora through various ways, modifying thus nutrients recycling. Myrica gale effect on microorganisms in the carbon cycle is studied in this work by comparing soil samples collected under the canopy in summer and control samples. The results indicate that under M. gale C-organic and N-total concentration and anaerobic cellulolytic, hemicellulolytic and amilolytic density increase, and pH, C/N ratio and aerobic cellulolytic microorganisms density decrease. Microbial activity in soil is also modified.
