【摘要】 野生百合作为资源保存,如何预防病毒的侵染依然是一个重要问题。从智利引种回来的东方百合品种Soldera和云南引种的Corvara中未检测到病毒,但从其早期生长状况看,这两个品种都表现有拟似感染病毒的特征,由于受检测引物的限制,本测试未检出,究竟是否携带病毒尚需进一步鉴定。云南引进的铁炮百合自身带有病毒,且发病率很高,传播也快,说明该品种为高感品种。本检测结果仅显示该品种携带LMoV,但根据其病状看,并未发现该病毒特有的叶片针状细化且丛簇,因此也可能为复合侵染,这尚需进一步研究。而来自福建的Siberia,则表现出多种病毒复合侵染。值得注意的是岷江百合既未发现病毒侵染症状,RT-PCR检测也均成阴性,说明岷江百合是一个抗病毒的珍贵种质资源。更多还原

【Abstract】 Wild Lily as a resource conservation, how to prevent virus infection is still an important issue. Oriental lily varieties Soldera introduced from Chile and Corvara introduced from Yunnan was not detected virus, but from their early growth situation,these two varieties have shown there seems to be characteristic of infection. The test not detected the virus due to the restriction of primer, so these two varieties whether carrying the virus needs to be further identification. Easter Lily itself with virus from Yunnan, and with the high rate of incidence, spread fast, which shows that the variety is a highly susceptible variety. The test results showed that the variety only carry virus LMoV, but according to its symptoms, it was not found specific needle-like leaves cluster of the virus, and therefore likely to be compound infection, which needed further study. And variety Siberia from Fujian showed compound infection of multi-viruses. It is worth pointing that Regel Lily neither discovered symptoms infected by virus, nor RT-PCR is positive, which showed that the Regel Lily is a valuable anti-virus germplasm.更多还原
