Multiple Infection of Clover Plants by Strains of the Nodule Organism in the Field

Abstract

THE possibility of obtaining, under experimental conditions, a simultaneous association of a leguminous plant with different strains of the nodule organism has been investigated by previous workers, with somewhat varying results1. So far as I am aware, the only published observations of multiple infection of a given legume plant in the field by strains of the nodule organism of different nitrogen-fixing powers are those included in the recent paper by Purchase and Vincent2 which refer to clover plants under Australian conditions. Prior to the publication of this paper, I had begun an investigation of this aspect in clover plants growing in the west of Scotland.
