蚜虫获毒酶联免疫吸附法(AA-ELISA)是指用ELISA测定从染病植株上获毒蚜虫以反映品种抗BYDV的方法。经对带Yd2基因大麦品种877-16与感病品种Manley对比测定,按其方法接种3叶期第1叶片,传毒3d后用无毒禾谷类蚜虫从第2叶片上取食获毒1d,采集5头作ELISA测定。AA-ELISA法测定OD值,Manley显著高于877-16,用ELISA直接测定无显著差异。用AA-ELISA法具有不破坏植株,可对同一部位重复测定,且蚜虫体软,易研碎抽提病毒,测定抗感品种差异明显等优点,具有适用性。
Aphid Enzyme-Linked Immunosorbent Assay (AA-ELISA) refers to the method of measuring the resistance to BYDV by using aphids collected from infected plants by ELISA. The first leaf of 3-leaf stage was inoculated according to the method of 877-16 with the Yd2 barley variety Manley and the susceptible variety Manley. After the virus was infected for 3 days, the non-toxic cereal aphid was taken from the second leaf for 1 day, 5 were collected for ELISA assay. The OD of Manley was significantly higher than that of 877-16 by AA-ELISA, and no significant difference was detected by ELISA. With AA-ELISA method does not damage the plant, the same site can be repeated determination, and aphids are soft, easy to crush virus extraction, determination of anti-susceptible varieties obvious advantages, is applicability.
