Water uptake analysis in Japanese mustard spinach: A numerical approach

We constructed an experimental system consisting of a syringe pump and water level feedback control to reveal the dynamics of water uptake in Japanese mustard spinach. We also analyzed differences in time-lapse images to quantify turgor movement in these plants. By performing harmonic analysis using the discrete Fourier transform on these dynamics, the frequency domain was obtained. These methods enabled the detailed visualization of plant dynamics. HighlightIn this study, the water uptake dynamics of Japanese mustard spinaches were measured in detail and image difference analysis was performed to investigate the plants turgor movements. Frequency domain analysis of the plant dynamics was carried out using a discrete Fourier transform.
