摘要
在山东青岛地区发现染病小蓟[Cephalanoplossegetum(Bunge)Kitam.]植株,轻者矮化,或不能正常开花结籽,重者死亡。病叶背面长满了锈色的孢子粉。病原经鉴定为蓟柄锈(Pucciniaobtegens)。首次对该病菌进行了详细地研究,以期为杂草小蓟的生物防治开辟新的途径。
In Qingdao, Shandong province we found that rust infected and harmed plants of Common Cephalanoplos Herb [Cephalanoplos segetum (Bunge)Kitam.]. This is the first time for scientist to investigate the pathogen in details, and the pathogen was identified to be Puccinia obtegens. The seriously infected plants are necrotic or stunted. Rust disease can readily be recognized when the orange-colored pustules or uredinia (uredia) appear on the abaxial (lower) surface of the leaves and rupture to expose masses of reddish-brown urediniospores (uredospores).The purpose of our investigation is to find a kind of bioherbicide.
