    The role of the bacterial rhizosphere in the limitation of the development of the pathogenic micromycetes of the roots of the tobacco plants

    PAUNESCU M.; PAUNESCU A.D.; STEFANIC G.
    Academy of Agricultural and Forestry Sciences, Bucharest, Rumania.
    The rhizosphere has a special position in soil biology, due to specific interactions between soil microorganisms and tobacco plants. During their growth tobacco plants compete with soil microorganisms for nutrition. However relations between plants...
