| 摘 要： | 采用PCR方法对甘蔗植株不同生长时期(幼苗期、分蘖期、拔节期、成熟期)、同一植株的不同叶片及同一叶片的不同部位(叶尖、叶中、叶基)分别取样进行宿根矮化病检测。结果表明:在不同甘蔗生长时期常规PCR方法都可以检测出宿根矮化病阳性植株;对呈阳性植株的不同叶片及同一叶片的不同部位检测均呈阳性,说明被检测甘蔗品种植株不同位置叶片对甘蔗宿根矮化病检测效率影响差异不明显。

| Abstract: | PCR was used to detect Leifsonia xyli subsp. xyli in sugarcane leaves collected from four growth stages (seedling stage, tillering stage, jointing stage and mature stage), different position of the same plant and three portions of each leaf. The results indicated that leaves from all four growth stages could be diagnosed as positive for L. xyli subsp. xyli infection. In addition, leaves in different positions from L. xyli subsp. xyli positive plants were detected as positive as well. So leaf position didn't affect L. xyli subsp. xyli assay efficiency in the detected sugarcane cultivar. |
