摘要
禾腥黑粉病（Ｔｉｌｌｅｔｉａｆｕｓｃａ）和小麦矮腥黑穗病（Ｔ．ｃｏｍｔｒｃｏｃｒｓａ）是我国尚未发生的危险性病害。由于主要形态学特征的交叉重叠，影响了两者病原菌的准确鉴定．本研究对进口检疫中截获的这两种病菌的形态、萌发生理以及网脊萤光反应进行了对比试验。提出了一些鉴别方法。探讨了禾腥黑粉菌与其变种及其近似种的比较和分类。
Both Tilletia controvcrsa Kubn and T. fusca Ell.& Ev. are dangerous diseases, which have not been found in China. Due to the similarity or the overlap of the main morphological char-。acters between the teliospores of these two species, it is very difficult to distinguish one from the other. In this study,teliospores of T.controvcrsa and T. fusca collected from the inport quarantine were tested and compared in morphology. germination physiology and ridge flouresence. Some im-proved identilication methods have been proposed. and the comparisons and classications among T. fusca and its closely related specles have been discussed.
