Development of rhizosphere and rhizoplane microflora of Aristida coerulescens in the Libyan desert

Summary Microflora of rhizosphere soil, rhizoplane and macerated root-portions of Aristida coerulescens, naturally occurring in the Libyan desert, were different in count and isolates, in the different root zones. A rhizosphere effect characteristic of each zone is shown. The root base contained the lowest numbers of microflora (bacteria and fungi) whilst the root tip included the highest counts. Distribution of most of the individual fungal species in the different root zones and root-surfaces is given in text.
