To provide a plant growing method and a plant growing system in which a plant having am increased content of an enhanced component in an edible part can be efficiently grown.SOLUTION: A water stress is given to a spinach Lg whose above-ground part is an edible part while promoting transpiration of the spinach Lg after a stable period of growth of the spinach Lg. In this case, humidity inside a plant cultivation facility where the spinach Lg is grown is adjusted in order to promote the transpiration. Further, a water level of a culture solution is maintained such that only tips of roots of the spinach Lg are immersed into the culture solution containing an enhanced component to be increased in the spinach Lg.SELECTED DRAWING: Figure 2 【課題】可食部において強化成分を増加させた植物を効率的に生育することができる植物生育方法及び植物生育システムを提供する。【解決手段】地上部を可食部とするホウレン草Ｌｇの成長安定期以降に、ホウレン草Ｌｇの蒸散を促進させながら水ストレスを与える。この場合、蒸散促進させるために、ホウレン草Ｌｇを生育する植物栽培施設内の湿度を調整する。また、ホウレン草Ｌｇの根の先端のみが、ホウレン草Ｌｇに増加させる強化成分を含む培養液に浸かるように、培養液の水位を維持する。【選択図】図２
