| Outline of Final Research Achievements |
This study presents a method for evaluating water content change in a leaf by using visible, NIR and THz spectral analysis. The spectral behaviors corresponding to the drought of water in the sample leaves were investigated. The band in the 1400-1460 nm were shifted to longer wavelength during water drought and the imaging showed the inhomogeneity of drying of leaf. Baseline shifted of THz spectra corresponded to the water contents in leaf. Thus the fundamental result of the band behavior under water stress was provided by this study, moreover water activity might enhanced the evaluation of stress by using non-descriptive methods.
