外稃

在接种后24h，当菌丝在外稃、内稃的内侧表面扩展而尚未侵入寄主细胞前，病菌已分泌DON，并且DON已扩散到寄主组织内。

Hyphae of the pathogen produced toxin when they grew on inner surfaces of lemma and palea as early as 24 h after inoculation , and the toxin was detected inside of host tissues at this time .

接种后36h，寄主体表菌丝产生入侵菌丝，以直接入侵方式由颖片、外稃、内稃的内侧及子房的顶部侵入寄主组织体内，随后，菌丝以胞间和胞内生长的方式向下扩展；

Penetration of host tissues occurred on inner surfaces of glume , lemma , palea and on the upper part of ovary by infection hyphae 36 h after inoculation . The hyphae in these infected tissues then spread downward to rachis by inter - and intracellular growth .
