Plant-soil interrelationship, factor of evolution for bacterial populations
Main Article Content
Abstract
The rhizosphere is influenced by the region, soil and plant roots. The area that is not influenced by plant roots
has been named edaphosphere. Plant roots release a wide range of compounds in the rhizosphere, which
create unique micro-environments for the microorganisms present in the soil. By its root exudates, species
Vicia sativa contributes to an increase in the bacterial density (fact proven by comparison with the control
variant), to the improvement of the fertility of the soil (moderately gleyic eutric cambisol) on which it is
cultivated and to plant growth. Even there are similarities between the rhizospheric area (culture medium:
soil extract), control variants, and respectively edaphosphere (culture medium: soil extract) and
rhizospherical bacteria isolated on Topping medium, small differences have been noticed.
