(1) Embryos separated from wheat seeds were transplanted on the endosperms of seeds precedentedly treated in dry condition for 20 hours with temperatures of 40°, 50°, 70°, 100° and 150°C, respectively. (2) Transplanted embeyos grew on the endosperms treated at 40°, 50° and 60°C just as well as on the untreated endosperms, but on those treated at 70°, 100° and 150°C, was the embryo growth remarkably retarded (Table 1). (3) Retardation of growth by the endosperm treatments at higher temperatures were considered due to the denature of enzymes rather than to that of growth substances or starch in the wheat endosperm.
