Induction of root nodules on Coriaria myrtifolia L. growing in water culture

Contrary to the experience of other workers, the authors succeeded in inducing nodulation of Coriaria growing in water culture by applying a crushed‐nodule inoculum. A possible reason for this success is that the Coriaria endophyte is intolerant of an acid rooting medium, which the authors avoided. The use of a habitat soil extract in the culture solution enhanced nodulation.
