Outline of Final Research Achievements

Agricultural production is limited by various factors, for example drought, temperature and CO2 elevation etc. In this study, we aimed to develop an imaging system to evaluate stress responses of plants. We used 3ch RGB sensors and recalculated for each spectral range. We measured such data using soybean leaves subjected to drought stress. As a result, there were significant differences of scattering coefficient spectrum between normal and drought stressed soybean leaves. This suggests that our method could be potentially useful to evaluate quickly plant's stress responses.
