| 中文摘要: |
| 为明确新疆不同地区造成棉花萎蔫,维管束变褐的病原菌种类及其发生现状,本研究对新疆47个主要植棉区有萎蔫症状且维管束变褐的棉花病株进行了分离鉴定,并对其快速分离鉴定方法进行了改进。结果表明:南疆20个地点,得到358个纯化菌株,黄萎病菌占81.8%,枯萎病菌占18.2%;北疆27个地点,得到495个纯化菌株,黄萎病菌占93.9%,枯萎病菌占6.1%。南北疆均以黄萎病为主,枯萎病南疆重于北疆。维管束病害的快速分离方法每分离一个样品只需2 min,污染率仅为6.7%。 |
| 英文摘要: |
| In order to identify the species and the occurrence of the pathogen which cause cotton wilting and vascular browning, cotton wilting and vascular browning plants collected from 47 main cotton planting areas in Xinjiang were separated and identified. And the isolation method was also improved. The result showed that 358 purified strains were obtained from 20 sites in South Xinjiang, Verticillium dahliae accounting for 81.8%, and Fusarium oxysporum for 18.2%. 495 were obtained from 27 sites in Northern Xinjiang, V.dahliae accounting for 93.9%, and F.oxysporum for 6.1%. Fusarium wilt in South is more serious than that in North Xinjiang. The improved isolation method only needed 2 min and its contamination rate was only 6.7%. |
