本试验于１９９６年对来自美国、加拿大和欧洲的１０６个小麦矮腥黑穗病菌（ＴＣＫ）和小麦网腥黑穗病菌（ＴＣＴ）菌瘿进行了冬孢子网脊高度值测量和自发荧光显微学观察。结果表明，网脊高度指数值（ＬＩ－Ｒ）可以准确地鉴别不同来源的ＴＣＫ菌瘿，准确率达９８．６％，而来源于美国和加拿大的ＴＣＴ菌瘿则有不同程度的错判。自发荧光显微学方法可准确地鉴别不同来源的ＴＣＴ菌瘿，准确率达１００％，同时也能较准确地鉴别不同来源的ＴＣＫ菌瘿，但不适合鉴别保存时间过长或已死亡的ＴＣＫ菌瘿。结合这两个特征，将能比较可靠地对菌瘿进行鉴别
In this study, telomere height measurements of 106 wheat (Triticum aestivum) and Triticum aestivum (TCT) from the United States, Canada and Europe were conducted in 1996 and the autofluorescence microscopy Learn to observe. The results showed that the network height index (LI-R) could accurately identify TCK strains from different sources with an accuracy rate of 98.6%. TCT strains from the United States and Canada were misjudged to some extent. Autofluorescence microscopy can accurately identify different sources of TCT bacteria, the accuracy rate of 100%, but also more accurately identify different sources of TCK bacteria 但, but not suitable for identification of long-term preservation or death of TCK Fungus. Combined with these two features, will be able to more reliably identify the bacteria 瘿
