Abstract
Replant problems cause both a poor development of fruit trees and a particular behavior of microorganisms in the rhizosphere.
Although the mycorrhiza-fungus is present, it has shown thin formations in the cortex and penetrates into the central cylinder.
As the microorganisms spread freely in the rhizosphere one can see a decrease of the total number of bacteria and fungus species.
In case of the replant problem, the enzymatic system of rhizosphere microorganisms for the same fruit species can be adapted and specialized.
Thus, the “soil sickness” may be due to the virulence of microorganisms in the rhizosphere, where VAM fungus plays a major role.
The cultural practices that contribute to the virulence attenuation of microorganisms, may also lessen the negative effects of replant problems.
