| Abstract: | Eighteen Frankia strains of actinomycetes with sporangia have been isolated from the root nodules of Casuarina equisetifolia , C.cunninghamiana and C.glauca by the tissue culture.The results of the pure culture on three media show that the BAP is the most suitable medium for the growth of Casuarina Frankia strains.The strains that have different characteristics of form and infection survive together in the same root nodule.Back inoculation experiments demonstrate that Frankia strains can not only crisscross infect young roots within different species of Casuarina ceae,but can also infect the seedlings of Myrica rubra and Alnus cremastogyne of other families to form root nodules. |
