| Outline of Final Research Achievements |
It is difficult to quantify the smoothness of the plant surface caused by environmental stresses, such as water stress. However, there is a possibility that features may be detectable through both the spectroscopic and polarized characteristics at wide range of wavelength. In this research, we first developed a simultaneous measurement system of spectroscopic and polarized characteristics. In addition, we measured the spectroscopic and polarized characteristics of plants with various stresses using the same system and examined the relationship with the change of the internal structure of plant tissues.
The results showed that in water stress stress experiments, it was confirmed that the process of cell destruction up to plasmolysis can be measured. Besides, in the experiment of photosynthesis experiment, the change of the structure of the tissue due to the accumulation of photosynthetic products such as starch granules can be measured from these characteristic.
