不同植物诱抗剂对烟草黑胫病和青枯病的防效
Control Effects of Different Plant Immune Inducers on Tobacco Black Shank and Bacterial Wilt
摘要
Abstract
This study aimed to screen high-efficiency and eco-friendly plant immune inducers for the control of black shank and bacterial wilt in the tobacco-growing area of Hunan Province.Pot experiments were conducted to evaluate the control efficacy of eight commercially available plant immune inducers.Additionally,the expression levels of defense-related genes,as well as the content of salicylic acid and jasmonic acid in the tobacco after inducer treatment,were determined.The results showed that Aitalin,Dyadex,and Pengbo Xihu exhibited favorable comprehensive control efficacy against tobacco bacterial wilt,with the control efficacy reaching 80.97%,94.45%,and 95.65%,respectively.Dyadex,Pengbo Xihu,β-aminobutyric acid(AIP),and pyrroloquinoline quinone(PQQ)showed outstanding control efficacy on tobacco black shank,with the control efficacy as high as 88.90%,89.48%,91.68%,and 92.65%,respectively.Subsequent studies revealed that all these five inducers activated the up-regulated expression of genes in the salicylic acid signaling pathway,and AIP,Dyadex,and Pengbo Xihu increased the salicylic acid content in tobacco.Dyadex and Pengbo Xihu both achieved high control efficacy against the two diseases.关键词
