摘要

In order to clarify the influence of chemical elements (Cd、Co、Cu、Zn and Mn) upon the growth of Pirioularia oryzae Cay, and Corticium Sasakii (Shirai) Matsumoto et Yamamoto, this experiment was made. The results will be summarized as follows:
1. It was found that Cd is one of the most toxic element to the growth of both fungi deseribed above.
2. When treated with concentration 10^(-3) Mol., Co and Zn were toxic to the growth of fungi, but no effect was found when treated with less than 10^(-3) Mo1.
3. It was found the copper chloride showed significant effect on the growth of fungi but not for other copper compounds under the concentration of this experiment.
4. Mn was found to promote the growth of fungi under condition of the present experiment.
5. Chloride salt was found to be the most toxic to the fungi within three kinds of salt used.
6. The order of inhibition of chemical elements on the growth of Pirioularia oryzae was found to be Cd＞Co＞Cu＞-Zn＞Mn, and that of Cortium Sasakii was Cd＞Co＞Zn＞Cu＞Mn.
