摘要 中英对照阅读
2019年夏季,伊朗克尔曼沙省一个10公顷的商业化土豆田(Solanum tuberosum)遭受了一种严重的茎枯病的影响。约有10%的植株表现出萎蔫、叶片变黄以及带有黑色孢子堆的棕色茎部病变的症状。受感染的植株产生的薯块较小,但没有明显的病斑。从患病植物中分离出的十个真菌菌株被鉴定为Paramyrothecium roridum,根据菌落培养、显微镜下特征和内转录间隔区(ITS)区域以及部分β-微管蛋白基因分析得出结论。通过完成柯赫法则确认了P. roridum对幼苗的致病性。寄主范围研究发现该P. roridum分离株具有广泛的致病性,能够成功感染各种植物物种,并表现出不同程度的疾病严重性。Cucumis melo(甜瓜)和Nicotiana rustica(野生烟草)显示出易感性,而Triticum aestivum(小麦)和Avena sativa(燕麦)则表现出抗病性。本研究将P. roridum确定为伊朗土豆茎枯病的新病因。
