Outline of Final Research Achievements

Research on improving the water use efficiency of plants is essential. In this research project, basic research was conducted to create plants that show high productivity under water-saving conditions. By combining chlorophyll fluorescence and thermography, we succeeded to construct a prototype of a visualization device for plant water use efficiency, which can simultaneously evaluate photosynthetic rate and transpiration rate. In addition, basic research for genetic improvement of water use efficiency in plants led to the discovery of several factors effective in enhancing plant productivity under water-saving conditions.

Academic Significance and Societal Importance of the Research Achievements

灌漑水を節減した条件下で、生産性を維持・向上する節水型農業が求められており、植物の水利用効率の向上に関する研究は必須である。本研究課題では、植物の水利用効率の可視化装置のプロトタイプを開発することができた。これによって、今後、植物の水利用効率の決定機構の解明と同時に、灌漑水の節減条件において高い物質生産能力を有する植物の創出を目指すことが可能となった。投入資源を節減しながら優れた生産性を維持し、かつ環境と調和した農業を目指していくことは、途上国における生産性改善に寄与するとともに、作物栽培の低コスト化や節水農業が推進されているわが国においても重要な方向といえる。
