Possibility of Decrease in Leaf Damage under Low Temperature Stress Due to Electric Current Loading

Abstract

Cryopreservation technique has attracted special attention from those interested in food shortage in near future. However, because plant is essentially desired to be preserved with living, it is said that cryopreservation of plant is especially difficult. We found the possibility of damage decrease effect under low temperature due to electric current load on plant tissue and reported the results before. This research followed the abovementioned report and investigated the possibility of similar damage decrease effect due to electric current load for the leaf scale-upped from tissue as that of tissue. This research discussed the measure to evaluate the leaf damage due to cold stress using a hyper spectrum camera. As a result, we found new index to evaluate the leaf damage. From the results of new index from spectrum intensity distribution, weight change ratio of leaf before and after the exposure under low temperature, it was clear that there was the possibility of damage decrease under low temperature due to electric current load on leaf.
