| 中文摘要: |
| 研究了小麦纹枯病菌在不同光照、温度、培养基条件下菌核数量形成的差异。结果表明，小麦纹枯病菌
在不同的光照条件下都可以形成菌核，但是形成菌核数量有差异。小麦纹枯病菌在24 h 光照（即G24）条件下产生的
菌核数量最多，其次是光照12 h，而在全黑暗（即G0）的条件下产生的菌核数量较少。小麦纹枯病菌在15耀35益条件下
都可以形成菌核，且在15耀30益的条件下，随着温度的升高，菌核数量也在增加，而在高于30益的条件下形成的菌核
数量在减少曰小麦纹枯病菌在25耀30益条件下最有利于形成菌核且数量较多。最适合小麦纹枯病菌形成菌核的培养
基是PDA 培养基。 |
| 英文摘要: |
| 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. |
