| Outline of Final Research Achievements |
Assimilation of 11CO2 to shoot for visualization of the rhizosphere of the plant and utilized it to make clear the role of rhizosphere by the exact place of secretion to rhizosphere soil. In lupin, the signal which resisted the formation position of the cluster root was clearly observed, and it was confirmed that a part of assimilation product was secreted via a root in a short time in the rhizosphere soil translocated from the assimilated part in shoot. As for the Leguminous crops, absorbing ability of radiocesium under potassium deficient condition is known to be high. However, the detailed mechanism is unclear, but some compounds secreted by a root and/or microbial activity changed the physico/chemical properties of soil is guessed. Plural compounds except the organic acid were secreted by potassium deficient condition became clear. On the other hand, it became clear that microbial species composition was greatly fluctuated even if just after assimilation.
