| 中文摘要: |
| 近年来，在甘肃省兰州市及渭源地区甘草产区发现一种甘草新病害—甘草叶斑病。2006－2008年对其发病情况进行了调查,甘草叶斑病在6月下旬开始发病，9月中旬为发病高峰期，发病率达80%。高燥地发病率低于低洼地，采用轮作可减轻甘草叶斑病的发生。经过对甘草叶斑病病原菌形态、培养性状和致病性等方面的测定表明，病原菌为豆链格孢（Alternaria azukiae）。通过寄主范围测定表明，该病原菌亦可侵染独活、羌活等药用植物。对大黄、苍耳等不具侵染性。 |
| 英文摘要: |
| In recent years, the disease causing leaf spot on Glycyrrhiza has been observed in Lanzhou and Weiyuan districts of Gansu Province. The incidence of Glycyrrhiza leaf spot disease was surveyed from 2006 to 2008. The results showed that the disease appeared in late June and became serious in mid September, with the rate of disease at 80%. The disease incidence of plants in uplands was lower than that in lowlands. Rotation could reduce the incidence of the disease. The pathogen was identified as Alternaria azukiae, according to the morphology, cultural characteristics and pathogenicity. The host range test showed that the pathogen could also infect Notopterygium incisum, Angelica biserrata and Datura stramonium. |
