摘　　要：独脚金属(Striga spp.)及列当属(Orobanche spp.和Phelipanchce spp.)杂草是世界范围内对农业生产危害严重的根寄生杂草,主要依靠寄生茄科、豆科、谷类等作物获得水分和营养。根寄生杂草种子只有在合适的萌发诱导物(如独脚金内酯)刺激下才能萌发。文章从根寄生杂草的分类、分布及危害,种子萌发剂类型及适用范围,种子萌发剂独脚金内酯的生物合成及分离鉴定,根寄生杂草种子萌发诱导剂的作用机制以及种子萌发过程中激素间协同调控作用等方面进行了综述,并展望了种子萌发剂设计筛选及其在根寄生杂草化学防控中的潜在应用前景。Root parasitic weeds such as Striga spp., Orobanche spp., and Phelipanchce spp. have caused significant losses in agriculture production worldwide. They extort water and nutrients from host plants, such as Solanaceae, Leguminosae, and grain crops, causing the shrinking and death of the host. Seed germination of root parasitic weeds is regulated by germination stimulants such as strigolactones. This report has summarized the current state of our understanding on the root parasitic weeds, the types of seed germination stimulants and their characterization, biosynthesis, and mode of action. Moreover, the perspective of using seed germination stimulants and their alike in the control of root parasitic weeds has also been discussed.
