| 摘 要： | 目的]探索叶褐斑枯病(Macrophoma sp.)的发生对巫山淫羊藿生长势与质量的影响,为防治措施的制定提供理论依据。方法]调查发病较重田块的病情指数、株发病率、叶片发病率、病株株高、分枝数、叶片数、叶宽、叶长等,同时取样作药材质量检测,比较分析病害的发生对生长势与质量的影响。结果]该病害的发生造成植株株高、分枝数、叶片数、叶宽、叶长等生长势减弱,其中对分枝数影响较大,其次是叶片数。病害的发生对药用部位叶,以及茎、根状茎和须根中朝藿定C和淫羊藿苷含量无影响。结论]叶褐斑枯病对巫山淫羊藿药材质量无影响,但能造成巫山淫羊藿植株生长势减弱,该病害发生对巫山淫羊藿生物产量影响极大。

Impact on Leaf Brown Spot on Epimedium wushanense Growth Potential and Quality |
| |
| Abstract: | Objective] The effect of the occurrence of leaf brown spot(Macrophoma sp.) on the Epimedium wushanense growth potential and quality was explored, which would provide the basis for the disease prevention and control.Method] The disease index, individual plant mor-bidity, leaf morbidity, the height of sick plant, number of branch per plant, leaf quantity, blade width, length of leaf, etc.in the heavy disease-occurring field were randomly investigated.At the same time, the quality of medicinal materials in the samples from the field was tested.The effect of disease on its growth and quality was comparatively analyzed.Result] The occurrence of disease could weaken the growth of plant height, number of branch and leaf per plant, width and length of leaf, etc., among which, the number of branch suffered the maximum influ-ence, followed by the number of leaf.However, the disease-occurring had not the effect on the leaf as medicinal raw material, the content of epi-medin C and icariin in stem and root.Conclusion] The quality of Epimedium wushanense as medicinal raw material is not affected by the dis-ease-occurring of leaf brown spot, but the disease-occurring of leaf brown spot resultes in the Epimedium wushanense plant growth potential-weak-ening, so, in the biological yield of Epimedium wushanense is enormously impacted while the disease occurres. |
