Micropropagated and ''frigo'' plants of strawberry were inoculated with arbuscular mycorrhizal fungi and with the rhizosphere bacterium Pseudomonas putida. An increase in growth and fruit production was observed as well as the species-specific interaction between the symbiotic fungus and the bacterium. Growth substrate composition (optimal content of commercial absorbent Zeolite) was shown to be important for a maximum growth response of inoculated plants.
