| Research Abstract |
Soybean’s wet injury is important obstacle in the production, however themechanism has not been clear. In this study, ‘low oxygenic condition’ was made artificially as a modelof wet soil with a hydroponic culture, various soybeans whose field-wet endurance were known, werestudied on the response for low oxygen. As results, the relationship between the response and the wetendurance was detected, and concluded that one of the main factor for soybean’s wet injury was lowoxygen. And cultivar-specific response for low oxygen, as like the reduction of leaf area or fine root,and the decline of root water uptake were found out.
