摘  要：
采用诱抗剂苯并噻二唑(BTH)对滇牡丹3种主要病害(牡丹红斑病Cladosporium red spot、灰霉病Grey mould和黑斑病Black spot)进行了诱抗试验,分析了发病指数、诱抗效果、生理等相关指标变化。结果表明:诱抗剂对滇牡丹3种病害诱抗效果显著,其中以红斑病的诱抗效果最佳,并确定出BTH的最佳使用浓度为100mg/L;在此浓度处理后,叶片病斑面积停止增长,边缘逐渐愈合,SAFR和MDA含量显著降低,可溶性蛋白、色素和相关酶系活力指标均显著增加,这些变化与病害的抗性变化密切相关。诱抗剂BTH对滇牡丹3种病原菌不产生毒杀作用,而是诱导植物系统获得性抗性(SAR),其作用机理有待进一步的研究。

摘  要：
The inducer BTH was been tested to three main disease(Cladosporium red spot,Grey mould and Black spot) of Paeonia delavayi Franch,and the infection index,induced-resistance effects and related physiological and enzyme activity indexes were analyzed. The results showed that the BTH had significant induced-resistance effects on the three main diseases. The optimal inducer effect was Cladosporium red spot and the best concentration was 100mg/L. The indexes of SAFR and MDA were dramatic decline,but the indexes of soluble protein,Pigment and related enzymes activity were obviously higher than those control processing,and these changeswere closely related with resistance induction of the main diseases. BTH did not have toxic function to the three pathogenic fungi,but lead to P. delavayi produce systemic acquired resistance(SAR) effectively,while its functional mechanism need to be further studied.
