| 摘 要： | 在自然条件下形成的大豆锈菌（Phakopsora pachyrhizi Sydow)冬孢子不能萌发直接浸染大豆，落入土中的病菌残体也不能引起大豆植株发病，说明在我国锈菌虽然能在自然条件下形成冬孢子，但不能成为大豆锈病初次侵染源。

| Abstract: | The teliospore of Phakopsora pachyrhizi Sydow formed under the natural conditions were unable to germinate and infect the soybean plant, neither did the residue in the soil. The result indicated that the teliospore could form in North China but would not be as the primary inocula of soybean rust. It has been proved that the primary rust inocula came from the uredosporea which spred with air current northward seasonally from South China. |
