| 摘 要： | 甘草(Glycyrrhiza uralensis Fish.)别名甜草、蜜草、甜根子, 为豆科多年生草本植物, 以根与根茎入药, 具有补脾益气、清热解毒、祛痰止咳、缓急止痛、调和诸药之功效, 是我国临床常用的中药材, 也可用作食品添加剂。甘草主要分布在我国的内蒙古、甘肃和宁夏, 在青海、陕西、新疆、黑龙江、辽宁、吉林、河北、山西等地局部地区也有分布。宁夏盐池县是我国乌拉尔甘草的重要产区, 面积大、贮量多、品质好, 1995年被誉为“中国甘草之乡” 1]。近年来, 野生甘草遭到了大规模采挖, 甘草蕴藏量急剧减少, 目前主要通过人工种植来满足市场需求。随着甘草种植面积的不断扩大, 甘草病虫害日趋严重, 根腐病危害尤为突出, 直接影响甘草的产量和品质, 造成巨大经济损失。 |

| Abstract: | The diseased roots of Glycyrrhiza uralensis with root rot symptom were sampled in Ningxia, China. Seventy eight fungal isolates were finally isolated from the materials and the pathogens were identified according to Koch’s postulate. Fusarium solani and Fusarium oxysporum were found to be pathogenic to G. uralensis plants. Based on the morphological characteristics and sequence analysis of EF-1α, the representative isolates G013 and FLR were identified as F. solani and F. oxysporum, respectively. The host range test showed that the two pathogens could also infect Solanum tuberosum and Glycine max, but not Triticum aestivum Linn, Vigna unguiculata, Medicago sativa, Phaseolus vulgaris, Cucumis sativus Linn, Solanum melongena L., Capsicum frutescens, Solanum lycopersicum, Zea mays L. and Gossypium spp.. This is the first report of root rot caused by F. solani and F. oxysporum on G. uralensis in China. |
