A Feature of the Root Nodules of Casuarina

Abstract

IN the course of an investigation into the development and physiological activity of the root nodules of Casuarina, considerable numbers of nodulated plants of C. cunninghamiana and C. equisetifolia are being grown in water culture. Nodulation was secured by inoculating the roots of young plants with a suspension of crushed Casuarina nodules obtained from abroad through the assistance of Dr. H. R. Fletcher, of the Royal Botanic Garden, Edinburgh, and commenced three to four weeks after such inoculation. McLuckie1 noted a resemblance between Casuarina and Myrica root nodules in that both show a lobed structure as the result of repeated branching (actually this is true of most non-legume and some legume nodules) and in that a root grows out from each nodule lobe.
