| Outline of Final Research Achievements |
Spectral distribution of the light emitted from the root of soybean irradiated with sunlight was measured using mini spectroscope C10083CA (Hamamatsu Photonics). Investigation of the spectral properties of the conducted light made it clear that only the spectral region between 700 nm and 940 nm was the most efficiently conducted. Branching of hyphae was enhanced by the direct irradiation of FR at 0.1 μmole/m2/s to the spores. Moreover, effect of FR irradiation to the shoots on the branching of hyphae located near the roots was investigated. FR enhanced hyphal branching even though with block the material trafficking between the roots and AM fungi. These results support the working hypothesis.
