摘  要:花椒,是我国著名的调料香味植物。我国是花椒种植大国,除东北、内蒙古以外其他各省自治区均有分布。花椒生长发育过程中,常受到流胶病、锈病、根腐病、枝枯病、菟丝子等的危害,直接影响花椒的产量、品质和经济效益,严重制约花椒产业的持续快速发展。有效防治花椒病害显得尤为重要。2009年河北省林科院花椒生产基地发生一种花椒新病害,Ten Zanthoxylum bungeanum ear blight diseased samples were collected from the Research Base of Forestry Research Institute of Hebei Province of China during 2009. Three isolates were obtained from diseased samples and no distinct difference could be observed among them. The fungus E-1 was determined to be responsible for this disease by the Koch' s Postulation. Morphological and the phylogenetic tree constructed based on ITS sequences showed that the morphological characters were the same as Alternaria alternata and the homology between E-1 and A. alternata was up to 100 percent. It indicated that E-1 was A. alternate (JQ973810).
