Abstract: | The mechanisms and testing methods of Ultraweak Bioluminescence are introduced. It is summarized that the research development of relations of UBL and seed vigor, variety specific characteristics, metabolism, growth development, green vegetable, etc., respectively. In agriculture, people try to use UBL as an index of testing saline-alkali resistance, drought resistance, heat resistance, cold resistance, and disease resistance. UBL provides a new acute physical way to breed and cultivate resistant variety, to explore the resistant resource. |
