| Outline of Final Research Achievements |
In greenhouse crop production, the local and opportune environmental control was examined from the viewpoints of spatiotemporal distributions of plant-environment transport processes such as leaf surface convection, photosynthesis and phloem transport regulating crop growth. The visualization of spatiotemporal distributions of plant-environment transport processes were enabled by newly developed methods such as the leaf surface convection sensor and RI imaging system. Based on these results, a system of the local and opportune environmental control for low light supplement and CO2 enrichment was newly applied, and its effectiveness was confirmed quantitatively from different viewpoints of productivity, energy saving and cost saving, and further to enable a year-round vegetable production in cold and warm regions, a system with the local and opportune environmental control was newly proposed.

| Academic Significance and Societal Importance of the Research Achievements |
作物生産場における葉面輸送プロセスの時空間変動の可視化およびRIのポジトロンイメージング技術によるソース・シンク間の転流動態の時空間変動の可視化等を初めて実現したことによって，種々の局所適時環境調節法の提示と，それらの多様な効果の定量評価と最適設計が可能となった．これらの，局所適時環境調節の方法論を導入することによって，野菜の施設生産における高収量・高品質安定生産，省エネ・省資源，省力・自動化，低コスト化に向けた環境調節の合理的な最適化が飛躍的に向上し，SDGsの達成にも寄与することが期待される．
