摘　　要：五味子属植物是我国传统的中药材。五味子春孢锈菌(Aecidium schisandrae J.Y.Zhuang)引起华中五味子(Schisandra sphenanthera)锈病为国内外新报道。该病在四川省雅安市喇叭河自然保护区华中五味子生长地造成严重危害,其病株率91％,病叶率36％,造成叶片枯斑、脱落。华中五味子锈病的重寄生菌(Tuberculina sp.)为国内外首次报道。该重寄生菌的自然重寄生率达35.5％,重寄生菌寄生在华中五味子锈菌春孢子器(锈子器)出口处,阻碍春孢子的释放。本文报道了华中五味子锈病的症状特点、病原形态特征及华中五味子锈菌的重寄生现象和重寄生菌的形态特征。Schisandra is Chinese traditional medicinal materials. The rust caused by Aecidium schisan-drae is an important disease of S. sphenanthera in LaBa River nature protective area. The percentage of diseased plant and the diseased leaf reach 91% and 36% respectively when the disease occurs seriously. The disease caused leaf spot, leaf cast and weakened the development of the tree. A hyperparasite (Tu-berculina sp. ) of A. schisandrae was first time reported. The natural hyperparasitic percentage averaged 35. 5 % in LaBa River nature protective area. The hyperparasites attack aecium of A. schisandrae and hinder the release of aeciospores. This paper reported the symptom of the rust and the morphological characteristics of the rust pathogen. The hyperparacitism and the morphological characteristics of the Tuberculina sp. were also reported.
