Abstract:

The report discusses a part of an investigation on Piricularia oryzae disease spanning the years 1942 to 1945. The study of P. oryzae involved the cultivation of the fungus - its growth and production were excellent - when there was no basic culture medium for the successful formation of spores. Even when this fungus was grown in the synthetic culture medium of Tochinai and Nakano which is frequently used in physiological investigations of filamentous fungi, the growth of fungus filaments was small and spores were not formed. However, when a rice straw broth was added to the culture medium, the cultivation of the fungus filaments was extremely successful and spores were also successfully formed.
