Outline of Final Research Achievements

We examined the usefulness of green light as a light source of artificial light plant factory. With respect to green lettuce cutivation, green light was effective in suppressing the decrease in chlorophyll concentration and rubisco concentration in the lower leaves. That is, there was an aging suppression effect of the lower leaves. In bean cultivation, the leaves turned yellow unless green light was introduced. The damage in the photosystem was considered mainly because there was no difference in the amount of rubisco between light treatments. A new fact has been found that green light is essential for the development of healthy leaves of beans.This study clarified that the need for green light varies with plant species.

Academic Significance and Societal Importance of the Research Achievements

人工光植物工場では赤色と青色の発光ダイオード(LED)が主に用いられている。それは緑色LEDの価格がまだ高いことによるが、植物栽培における緑色光に必要であるかどうかは明確にされていなかった。本研究により、リーフレタスでも品種により必要性は異なり、赤系リーフレタスには用いないほうが良いこと、緑系リーフレタスには下位葉の老化抑制に効果があることから必要であることがわかった。これは緑系リーフレタスにおいては生産の歩留まりを上げる効果がある点で、非常に有用な情報であると考えられ、その意義は高いものと考えられる。
