本文报道了梨胶锈重寄生菌（TuberculinavinosaSacc）对苹果锈病菌（GymnosporangiumyamadaiMiyabe）的寄生、形态特征及侵入。重寄生菌在苹果锈病菌的性子器旁及性子器相对叶背发生重寄生现象，将锈孢子封在锈子器内，从而对病害的侵染循环起阻碍作用而控制病害的发生。描述和测量了重寄生菌的产孢结构形态及大小。重寄生菌的分生孢于萌发形成芽管，经性子器口侵入，不能直接侵入。完成侵入所需最短时间为7小时。在20．6℃和22．1℃下，潜育期为8天和7天。
This paper reports the parasitism, morphological characteristics and invasion of Tuberculinavinosa Sacc against Gymnosporangium yamadai Miyabe. Parasitizing bacteria in apple rust fungus next to the device and the nature of the leaves relative to the back of the occurrence of heavy parasites, the rust spores sealed in the rust within the device, thereby inhibiting the disease cycle of infection impede the occurrence of disease control. Described and measured the sporozoite sporozoite structure and size. Sporozoites in the germination of the parasite spore formation of germ tube, invasive by the sperm mouth, can not directly invade. The minimum time required to complete the intrusion is 7 hours. At 20.6 ° C and 22.1 ° C, the incubation period is 8 days and 7 days.
