用苯并噻二唑-7-碳硫酸甲酯（BTH）处理南巴湾和台农芒果果实。通过评价BTH处理对芒果采后果实中抗性物质的影响，探讨不同品种BTH增强芒果果实抗病能力的机理。结果表明，不同品种经BTH处理后，主要抗性物质总酚、类黄酮、木质素和富羟基脯氨酸糖蛋白（HRGP）含量均明显增加。但抗性物质的增加，台农芒果高于南巴朗湾芒果。与此同时，未经BTH处理的台农果实中这些抗性物质的含量均高于南巴朗湾芒果果实，尤其是酚类化合物和木质素的含量。
Nang klangwan and Tainong mango fruits were treated with benzo-thiadiazole-7-carbothioic acid Smethyl ester (BTH). The effect of BTH treatment on the resistant substance in postharvest fruits was evaluated to explore the enhanced disease-resistance mechanisms of mango fruits by BTH from different varieties. Results indicate that the main resistant substance such as total phenolic, flavonoid, ligin and hydroxyproline-rich glycoprotein (HRGP) content were obviously increased by BTH treatment in different varieties. However, the increase in resistant substances of Tainong mango fruit was higher than that in Nang klangwan fruit. At the same time, Tainong fruit without BTH treatment had relatively higher level of these resistant substances than Nang klangwan mango fruit, especially in the contents of phenolic compounds and lignin.
