Effect on Inculation of Forms and Storage Methods of Casuarina Frankia inoculum

Significant advances have been made in the development of peat based,vermiculite based and alginate bead Frankia inoculum. Investigations of storage conditions for peat,vermiculite and alginate Frankia inoculum showed that the inoculant of Frankia 9022 in vermiculite maintained high viability and infectivity for up to 6 months when stored at room temperature;the inoculant of Frankia 287 in alginate bead maintained high viability and infectivity for up to 6 months when stored at 4℃. Determination the number of potentially infective units for Frankia 9022 vermiculite inoculant of 24 months storage at room temperature were 4.8×103/g inoculant.
