Some experiments on the artificial induction of injury, same to the one found at the region of Shigarami, were conducted by the author using a refrigerator. The results of the experiments were as follows: 1) The same type of the injury caused by the chilling at the region of Shigarami could be induced by treating wheat variety Norin No. 27 at the heading stage with a low temperature of 1-2℃. for 4 hours. 2) Only the ears at the heading stage among various stages were found to receive the greatest injury by the treatment. And the ears at a stage few days earlier orlater than the heading stage received no injury. 3) The threshold temperature by which the injury arises was somewhat different according to wheat varieties, physiological conditions of plant, and air moisture in the refrigerator. Under a certain condition, the occurrence of the injury required a low temperature 0℃.
