摘　　要：[目的]初步研究草茎点霉毒素Ⅲ对鸭跖草叶片的致病机理。[方法]提取鸭跖草离体叶绿体,通过离体叶绿体光合放氧量测定毒素对希尔反应活力的抑制率。[结果]随着毒素质量浓度的增加,对鸭跖草叶绿体希尔反应的抑制率逐渐增强,毒素质量浓度达到2 000 mg/L时希尔反应活力下降最高,达65.82%。[结论]草茎点霉毒素Ⅲ对鸭跖草叶片希尔反应活力具有强烈的抑制作用。[Aims] Preliminary studied the pathogenic mechanism of toxin from Phoma herbarum to Commelina communis. [Methods] Extract isolated chloroplasts, inhibition rate of hill reaction activity was measured with the release of photosynthetic oxygen for isolated chloroplasts. [Results] With the increase of concentration of toxin, inhibition rate of hill reaction activity to isolated chloroplasts was increased gradually, when the toxin concentration reached 2 000 rag/L, hill reaction activity down to a maximum of 65.82%. [Gonclusions] The toxin ofP. herbarum to C. communis hill reaction activity possessed strong inhibitory effect.
