| In this paper, the number of sclerotia in Rhizoctonia cerealis was studied under different illumination,
temperature, medium conditions. The results showed that R. cerealis could form sclerotian in different light conditions, but
there were differences in the number of sclerotian. The most suitable sunlight condition for forming sclerotian was 24
hours of sunlight, followed by light for 12 hours, while R cerealis produced less sclerotian in the dark. Sclerotia of R.
cerealis could be formed at 15-35. With the temperature increasing, the number of sclerotia increased at 15-30, while
the number of sclerotia reduced at above 30. The most suitable temperature for forming sclerotian was 25-30. The
most suitable medium for sclerotia forming of R. cerealis was PDA medium. |
