输入小麦中经常存在着相当数量的禾本科杂草种子,扩大了小麦矮腥病菌的传入寄主,也增加了某些禾草腥黑穗病随同传入的可能性。根据小麦矮腥病菌与某些禾本科腥黑穗病菌在动态方面的近似,以及在冬孢子萌发生理、寄主范围等方面的共同点,结合进口检验中禾本科杂草种子的出现频率,提出 Tille-tia caries,T.secalis,T.decipiens,T.fusca,T.elymi,T.lolii 等六种禾本科植物腥黑穗病菌为小麦黑腥病菌的近似种。
The importation of a significant amount of grass weed seeds in wheat often increases the incoming host of the wheat dwarf bacteria and increases the likelihood of some of the straw tipped disease coming along. According to the dynamic similarity between the wheat dwarf bacteria and some Graminaceae, and the similarities in the physiology and host range of winter spore germination, combined with the appearance frequency of weed seeds in the import inspection, we proposed Tille -tia caries, T. secalis, T. decipiens, T. fusca, T. elymi, T. lolii, etc. Six species of gramineous plants of the gramineous species are the approximate species of wheat black-tipped bacteria.
