摘　　要：Biophoton emission from germinating soybean under adverse circumstance has been observed by high sensitive imaging system based on ICCD detector. It is found that the intensity of biophoton emission from the injured position of the cotyledon is enhanced obviously compared with the intact position. In addition, a strong biophoton emission has been detected at the tipBiophoton emission from germinating soybean under adverse circumstance has been observed by high sensitive imaging system based on ICCD detector. It is found that the intensity of biophoton emission from the injured position of the cotyledon is enhanced obviously compared with the intact position. In addition, a strong biophoton emission has been detected at the tip of the root when the root is supplied with water after drought. The emission induced by wounding may be associated with the defense response of plants. The emission during the process of convalescence after drought may be the results of the changes of oxidative metabolism in cells.
