摘要:: 利用烟草-花叶病病害体系检测苯并噻唑硫代乙酸甲酯(benzothiadiazoles，BTH)、金针菇(Flammulina velutipes)发酵液提取物(JZG)诱导抗病作用。试验用盆栽珊西烟(Nicotiana tobacum，Xanthi-nc)为材料，用诱导剂处理烟草第6片叶，然后在上部未处理叶接种烟草花叶病毒(TMV)，结果发现上部叶片产生的TMV枯斑数与对照相比显著减少，说明这2种诱导剂能诱导烟草植株产生系统抗病性。同时研究了BTH、JZG作为诱导剂处理烟草后寄主内几种抗病相关酶的变化，结果表明烟草叶片组织中的几丁质酶、β-1，3-葡聚糖酶活性增加，且酶活性可在处理后15 d内维持高于对照组的水平。
