Indicated that the amount of nitrogen fixation carried out by a nodulated plant depended on several factors succh as number of nodules, the volume of bacteroid-containing tissue in each and the time for which this tissue persisted

Proved that Astragalus sinicus and its root-nodule bacteria (Mesorhizobium huakuii) must be considered as a select cross-inoculation group
