| Outline of Final Research Achievements |
The purpose of this study is development of a new control technique of function of woody root system by using light illumination. Tea cuttings were used as experimental materials. Effects of light illumination (wavelength: red, green, blue, white) by using LED on electric potential (EP), respiration activity of whole root system measured by TTC method (RA), total root length of each root cuttings (TRL), and expression of proteins in roots were examined. Largest changes were obtained on EP by blue light illumination, on RA by green one, on TRL by red one. These results suggest root system recognized illuminated light information and changed its functions.

| Academic Significance and Societal Importance of the Research Achievements |
根系機能を光により制御することを目指すには、草本植物を使う方が早道と思われるが、生理生態が異なる樹木において特に求められる技術開発を行うためには、初めから樹木根系を対象にすべきと考える。本研究により樹木根系を光によりコントロールすることが可能となれば、茶樹・果樹などの工芸分野から街路樹・森林木などの樹芸・森林科学分野に至る樹木を対象とする幅広い分野への応用が期待され、その波及効果も大きい。また樹木根系が光を認識してその機能を変化させるという知見は、学術的にも画期的であり、その意義は極めて大きいと考える。
