Studies on legume nodule bacteria: I. variations in strains of clover nodule bacteria; II. effects of calcium in media on clover module bacteria; III. nodule bacteria of various legumes of Scotland

Abstract

For convenience of presentation the thesis has been divided into three sections -- I. Variation in Strains of Clover Nodule Bacteria; II. Effects of Calcium in Media on Clover Nodule Bacteria; and III. Nodule Bacteria of Various Legumes of Scotland. In the first is discussed certain aspects of clover inoculation and field and glasshouse trials of strains of legume organisms in both New Zealand and Scotland. The second covers work on the effects of culture media on characters and efficiency of strains of the clover organism. In the third section an outline is presented of the nodule organisms of Scottish legumes together with an analysis of the classification of nodule bacteria.The outbreak of war unfortunately necessitated a return to New Zealand before these studies were completed; with the result that certain phases of the work had to be finalized in the Dominion. While at Edinburgh the work was carried out under the direction of Professor T.J. Mackie and Dr. T. Gibson of the University of Edinburgh
