大多数植保索化合物为脂溶性,其活性检测往往采用孢子发芽法和菌丝称重法。本研究以甘薯块根感染根腐病后产生的一类呋喃类萜植保素为材料,对其活性检测的方法进行了探讨。 Most plant-care compounds are lipid-soluble, and their activity tests are often spore germination and mycelial weighing. In this study, a kind of furanoid terpene phytoalexins produced after the root rot infected sweet potato tuber was used as material, and its activity detection method was discussed.
