| Outline of Final Research Achievements |
In order to investigate the response characteristics of the water and substance transport mechanism in plants to mechanical stimuli, the leaves were perforated and the leaf response was visualized using a visualization dye by blocking the water supply channel. As a result, it was found that water could be supplied if at least one vein near the stalk remained. In addition, it was found that the main component of water supply is a network of leaf cells, and transpiration by stomata can lift water even without roots. In order to confirm this, the model which attached the porous material of the micropore to the tube was made, and the experiment which made the possibility of water absorption by transpiration carried out was conducted. As a result, it was confirmed that water could be absorbed by transpiration even without roots.

| Academic Significance and Societal Importance of the Research Achievements |
例えば送電ネットワーク、情報ネットワーク、送水ネットワークなどにおいて、ロバストなインフラネットワークの構築に寄与できる。また、ポンプがなくても蒸散によるマイクロ吸水システムを構築できる可能性がある。電気が使えなくなくなった状況において、給水システムの構築に寄与できる。
