稻曲病是由稻绿核菌Ustilaginoidea virens（Cooke）Takahashi（有性态为Claviceps oryzae-sativae Hashioka）引起的水稻穗部真菌性病害，在世界各水稻种植区普遍存在。稻曲病不仅造成水稻产量损失，而且其产生的稻曲毒素对人、畜有害。该病已成为水稻上的重要病害。因此，稻曲病的防控和该病菌生物学特性已成为近年的研究热点。

The surface and internal structure difference of yellow and black dormant chlamydospores of Ustilaginoidea virens on mid-and late-season rice were examined by scanning electron microscopy(SEM) and transmission electron microscopy(TEM).SEM revealed that the spherical yellow and black chlamydospores had prominent spines, with the diameters from 3 to 6 μm and 4 to 6 μm, respectively. The spines were 200-700 nm and 400-1 100 nm long in yellow and black chlamydospores, respectively. Variance analysis showed that there was no difference in diameter...
