In Yamase area, Pacific coastal area of Aomori and Iwate Prefectures, soybean dwarf disease caused by soybean dwarf virus (SDV) is a very serious problem for soybean production. However, in that area, we found that soybean plants which showed wrinkling leaves, one of the symptoms of dwarf disease, were always infected with neither SDV nor other viruses and restored to health under warm condition. So it was thought to be a physiological disorder.<BR>Experiments were conducted to examine whether this disorder was induced by low temperatures. As a result, we demonstrated healthy soybean plants showed wrinkling leaves under the condition of low temperatures. This suggested that leaf-wrinklings were not always associated with SDV infection. Hence observation of yellowing of lower leaves, the other symptom of dwarf disease of soybean, or enzyme linked immunosorbent assay should be done for diagnosing dwarf disease of soybean.
