| 摘 要： | 检测表明京双16、聊89-1、聊89-2、聊91-1、聊91B18-27-1及鲁麦12 6个小麦品种(品系)的黑胚病病粒率为7.6%~45.7%,病情指数为3.2%~13.5%,以聊89-1最轻,鲁麦12最重。借助光学显微镜和扫描电子显微镜对6个品种(品系)的黑胚种子和健康胚种子进行了比较观察,证实了黑胚种子胚中链格孢菌(Alternaria)的存在,此外,亦观察到了黑胚种子寄藏有类似于长蠕孢属(Helminthosporium)、枝孢属(Cladosporium)等真菌的菌体。

| Abstract: | Six
varieties(lines) of wheat Jing Shuang 16, Liao 89-1, Liao 89-2, Liao 91-1, Liao 91B18-27-1, and
Lumai 12 were tested for black embryo disease by means of specimen examination with
microscope and SEM. Their percentage of black end seeds was 76%-457%, (disease index)
32%-135%. Liao 89-1 and Lumai 12 were damaged resulting in weak and serious symptoms.
Alternaria from embryo of black end seeds was identified under microscope while other seed
borne fungi such as Helminthosporium and Cladosporium were further discovered by SEM |
