In our earlier report, the results demonstrated that the addition of mechanical stimulation by artificial wind and vibration was related to an increase in the amount of moisture transported in the plant. The increased amount of moisture transported in the plant will activate photosynthesis and increase the absorption of nutrients from the roots. Based on those earlier results, the present study entailed providing artificial wind via mechanical stimuli to the Komatsuna plant (botanical name : Brassica campestris) and examining the relationship between the amount of growth (leaves area and total weight) and the photosynthetic rate in this plant. We used 1, 10, 30, 60 and 120 minutes as wind periods, with an artificial wind of 0.5m/s. For example, a 30-minute wind period consisted of 15 minutes of wind time and 15 minutes of windless time. As a result, we confirmed that both the photosynthetic rate and the amount of growth with artificial wind during the 30-minute wind period increased compared to the windless case. This result was qualitatively proved by the simulation of photosynthetic rate using the electrical circuit model.
