| Research Abstract |
Highly sensitive optical interferometer named Statistical Interferometric Technique (SIT) was developed to measure ultra-short term growth dynamics of plant leaves in temporal scale of second. Paying a special attention to crops under exposure of photochemical oxidant, the technique was applied to monitor ozone stress of crops, e.g., rice plants. It was proved that the technique was valid to monitor the stress of crops under ozone exposure much faster than the conventional methods. In addition, it was possible to distinguish the tolerances for ozone between the cultivars of crop.
