对美国135个小麦矮腥黑穗病菌(Tilletia controversa Kuehn,以下简称TCK)及小麦网腥黑穗病菌(T.caries Tul.以下简称TCT)进行的比较形态学研究表明,网脊高度最具有鉴别意义。在中美双方所测的近万个数据中,TCK与TCT菌株的平均网脊高度值很少交叉,两个种在网脊高度上的区别具有种间的规律性和鉴别性。经人工污染样品及市场样品对各种模型的检测证明,根据逻辑方程推导出的临界网脊值可用于市场样品检验中对TCK的判别和鉴定,从而为准确、快速地鉴定进口粮中少量的或混合的TCK、TCT冬孢子提供了新途径。
A comparative morphological study of 135 Tilletia controversa Kuehn (hereinafter referred to as TCK) and T.caries Tul. (Hereinafter referred to as TCT) in the United States showed that the height of the network ridge is most discriminating significance. Among the nearly 10,000 data measured by China and the United States, the mean net ridge height values of TCK and TCT strains rarely cross each other. The differences in net ridge height between the two species are inter-species regularity and discrimination. The testing of various models by artificial contaminated samples and market samples proves that the critical ridge values derived from the logic equations can be used to identify and identify TCK in the market sample test so as to accurately and quickly identify a small amount of Or mixed TCK, TCT teliospores provides a new way.
