| 摘 要： | 为研究东莨菪素（一类香豆素类植物保卫素）对大豆灰斑病的防治效果，本研究通过室内试验，盆栽试验和田间小区试验，调查了东莨菪素对大豆灰斑病的防效及促生作用。结果表明：东莨菪素对灰斑病菌有显著的抑制效果。在东莨菪素浓度为8.10 mg/L时对灰斑病的诱抗效果较好，且处理后的大豆叶片内东莨菪素含量显著上升，在田间试验中，对株高、鲜重、主根长等生理指标有促进作用，且抗病性显著增加。

| Abstract: | Scopoletin is a kind of plant defensins, which belongs to coumarin. To investigate the prevention effect of scopoletin on gray leaf spot disease caused by Cercospora sojina, indoor antagonism, growth promotion, germination experiments, as well as pot and field plot experiments were conducted. It verified that scopoletin had a good control effect on gray leaf spot disease. Our results suggested that scopoletin inhibited the gray spot pathogen significantly. With a concentration of 8.10 mg / L, scopoletin could reach the best inducing resistant effect on gray spot disease, meanwhile the endo content of scopoletin in leaf increased significantly. In the field experiment, scopoletin promoted physiological indices of soybean plant, height, fresh weight and lenth of main root, which accompanied with a significantly enhanced resistance to gray leaf spot disease. |
