腥黑穗病

Result The detection limit of the two systems were 0.1fg, equal to 2.31×10^4 copies, which was 10^2-10^3 fold higher than conventional PCR. By the constructed detection systems, the TCK and Tilletia cariesTul could be distinguished. The teliospore and mycelium of TCK in the infected wheat plant tissue also could be identified accurately and rapidly.

建立的两套定量PCR检测体系的检测下限相当，可达到0.1fg，对应的拷贝数为2.31×10^4个，检测灵敏度比常规PCR高2~3个数量级，均可成功鉴别出TCK与小麦网腥黑穗病菌Tilletia caries (DC Tul， TCT，并可快速准确检测小麦矮腥黑穗菌冬孢子和检测罹病小麦植株体内的侵染菌丝体。

The relationships between germination of the teliospores of Tilletia conroversa Kühn and soil moisture were studied and it was found that the teliospores of TCK could germinate when the soil mass moisture content reached between 1%-28%(relative moisture capacity 3.75%-100%). The suitable moisture for teliospore germination was between 10%-25% of mass moisture capacity or 17.85%-89.3% of relative moisture capacity. The optimal soil relative moisture capacity was between 65%-75%. There was no difference among most TCK isolates tested at the same suitable soil moisture.

通过土壤湿度对小麦矮腥黑穗病菌( Tilletiacontronversa Kühn，TCK)萌发率的影响试验研究表明，其冬孢子在土壤质量含水量为1%～28%(相对含水量3.57%～100%)范围内均可萌发，其适宜萌发的土壤质量含水量范围为10%～25%(相对含水量17.85%～89.3%)，最佳土壤相对含水量范围在65%～75%之间；不同分离物在相同土壤湿度培养下，多数分离物冬孢子的萌发率之间差异不显著。
