| 中文摘要: |
| 温郁金炭疽病是一种重要的真菌性病害, 该病主要危害叶片, 初期产生水渍状的淡黄色病斑, 后逐渐扩大成圆形、椭圆形或不规则形的灰褐色病斑, 上面有黑色小点, 病斑外面环绕一层黄色晕圈, 严重时多个病斑联合造成叶片卷缩和枯死, 2016年我们从海南省的温郁金种植基地采集炭疽病样本, 经病原菌的分离纯化、柯赫氏法则验证、病原菌的形态特征观察及多基因谱系分析方法, 确定其病原菌为郁金炭疽菌Colletotrichum curcumae (Syd.) E.J. Butler & Bisby。 |
| 英文摘要: |
| Curcuma wenyujin anthracnose is an important fungus disease on leaves. The symptoms began as water-soaked and canary spots, followed by becoming brown, round, elliptical or irregular lesions with lots of black dots, and then being surrounded by a clear yellow halo. These spots enlarged and overlapped, extending until the leaves withered entirely. The samples of diseased leaves with the anthracnose syndrome were collected from the Curcuma wenyujin Planting Base in Hainan in 2016. Through pathogen isolation and purification, pathogenicity test, morphological characteristics and multi-gene phylogeny analyses, the pathogen was finally identified as Colletotrichum curcumae (Syd.) E.J. Butler & Bisby. |
