The constant strains of the Koji molds, S- or F-types, form conidia with comparatively uniform sizes; i, e. S=3_??_5<i>μ</i> and F=4_??_6μ. The inconstant strains, on the contrary, produce conidia rich in variety of sizes, including those with unordinarily large diameters (3_??_10μ or more).<br> 2. The conidia of the constant strains have been found to contain 1_??_4 nuclei, the majority containing two nuclei. The conidia of the inconstant strains, however, are exceedingly multinucleate (8_??_20 or more) and large in diameters as shown in the Plate.<br> 3. In the constant strains, one nucleus moves into conidium from apex of the sterigmata at the beginning of the conidium formation, and divides at once into 2_??_4 through probable mitotic divisions. While in the inconstant or variable strains, more than 2 conidia migrate from sterigmata into newly formed conidium. Those conidia become multinucleate (8_??_20 or more) promptly through repeated divisions of nuclei.<br> 4. As to the migration of ndclei from vesicle, which is conspicuously multinucleate, into sterigmata, the authors have recognized that in the constant strains always only one nucleus migrates into sterigmata while in the inconstant strains at least 2_??_4 simultaneously, the sterigmata becoming much more long and broad consequently.<br> 5. From the facts above shown it might be assumed that the variability of the inconstant strains of the Koji molds chiefly depends upon the multinucleate property of the conidia."},{"@value":"(1) 麹菌のうちで変異しにくい固定した株(constant strain)はS-typeもF-typeも共に胞子形齊一S(3～5μ)F(4～6μ)で,変異を生じやすい株(inconstant strain)のX-typeは胞子の大型のもの多く,その直径の範囲が著しく広い.
