Induction of antimicrobial compounds in alfalfa callus by cell wall components fromFusarium oxysporum

Callus cultures ofMedicago sativa were treated with a preparation of elicitor from the mycelium ofFusarium oxysporum. The ability of the elicitors to induce the formation of antimicrobial substances was tested biologically. The preparation of the cell walls ofF. oxysporum induced the occurrence of substances with a strong antimicrobial effect. Thermal sterilization had no effect on the activity of the elicitor.
