Abstract
Cryopreservation technique has attracted special attention from those interested in food shortage in near future. However, because plant is fundamentally preserved with living, it is said that cryopreservation of plant is very difficult. Therefore, the estimation of plant damage is very important under low temperature in order to develop the cryopreservation technique of plant. This research investigated the possibility of damage estimation to plant in terms of normalized difference vegetation index (hereafter NDVI). This research consisted of two experiments. First experiment measured NDVI change of plant (leaf) under room exposure for several days in order to understand the relationship between NDVI and plant damage. Second experiment measured NDVI change under the exposure of low temperature. As a result, it is clear that there is the possibility of damage estimation of plant using NDVI.
