摘　　要：以萱草属3个野生种和84个栽培品种为试材,研究了萱草属植物类黄酮化合物与抗蚜性的关系。结果表明:危害萱草属植物的蚜虫为金针瘤蚜(Myzus hemerocallis);蚜虫密度<0.5头/cm2的萱草品种达41个,其中野生种萱草和栽培品种萱草"紫绒"蚜虫密度均为0。不同种类、品种萱草叶片中类黄酮化合物组成和含量存在较大差异,其中异鼠李素-3-O-葡萄糖-7-O-鼠李糖苷与蚜虫分布密度显著负相关,槲皮素-3-O-半乳糖苷与蚜虫分布密度显著正相关。With 3 wild species and 84 cultivars of Hernerocallis L. as materials, the relationship between flavonoids and aphid resistance were discussed in this study. The results showed that the aphids harm to Hernerocallis were Myzus hernerocallis. Cuhivars with less than 0. 5 aphids/cm2 were up to 41 ,among of which H. fulva and H. ＇Zirong＇ were no found aphids. There were significant differences in flavonoids＇ composition and contents among different species and eultivars of Hemerocallis. Most of detected flavonoids had no significant correlation with the density of M. hemerocallis. Only Isorhamnetin-3-O-glucose-7-O-rhamnoside had negatively correlationship with aphid density,while Quereetin-3-O- galactoside had significantly positive correlation with aphid density.
