鉴定小麦矮腥黑穗病Tilletia controversa Kuhn与小麦网腥黑穗病Tilletia caries Tul.的重要手段是进行冬孢子萌发试验,但这种方法需要的时间长,不能够适应进口粮检疫的需要,因此,对用形态学区别它们的研究引起了许多植物检疫工作者的重视,已经报道的运用外部形态的某些观察值所占百分比来区别它们的方法为鉴定它们找到了一条新路,笔者运用数理统计的原理,试图从两种冬孢子的网脊分布型入手,找出其分布特点,旨在把它们区别开来。
Identification of Tilletia controversa Kuhn and Tilletia caries Tul. Is an important measure of teliospore germination, but this method takes a long time and can not meet the needs of imported grain quarantine , The study of morphological differences between them has drawn the attention of many plant quarantine workers. The reported percentage of some observations using external forms to distinguish them has found a new way to identify them. The author uses mathematical The principle of statistics, trying to start from the distribution of the two types of teliospores net ridge, to find out its distribution characteristics, designed to distinguish them.
