Abstract english

The growth of 10 isolates of rhizosphere bacteria was compared in the rhizoplane (RP), rhizosphere (RS) and non-rhizosphere soil of a model system with rape seedlings growing in sterile sand. The colonization of the RP differed little among isolates. However, the bacterial isolates differed according to their degree of dependence on the root for growth, as judged by RS:RP and plant:non-plant ratios for CFU. These two ratios were correlated with changes in viability and 'physiological status' (as judged by γ values, Hattori, T. (1983) J. Gen. Appl. Microbiol. 29, 9-16).
