Planted rice seedling in early spring at frame during 1957 to 1958 but many TTUNMYO(Mureaoae) occured at frame nursery, so writer to find cause of its occuring.
Experiments were carried under the artificial growth circumstance; Card-board-box, Glass-box. Different temperature of water irrigated. 1/20000 Wagner pot used.
The TTUNMYO occurred by the difference of soil temperature and frame room temperature, and always requires to keep soil temperature and frame room temperature eqully for prevention of its occurrence.
