| 摘 要： | 连续3a对不同来源的玉米种子,利用显微镜镜检和试种观察植株发病显症的方法,检测其携带玉米疯顶病病菌状况。结果表明,病株病穗籽粒、病株健穗籽粒、病田健株籽粒都有较高的带菌率。因此,病菌随种子调运远距离传播是造成各地病害突发的主要原因。

| Abstract: | The status of corn seeds Sclerophthora macrospora (Sacc) Thirum., Shaw & Naras from different growing area was detected for consecutive three years by using the methods of microscope observation and symptom observation in growing period. The results show that seeds from diseased spike of diseased plant, healthy spike of diseased plant, and from healthy plant in diseased field were higher fungal-bearing rate. The outbreak of corn crazy top in different areas was mainly caused by the long way transportation of the diseased seed. |
