摘要: 本文对梨胶锈菌(Gymnosporangium asiaticum Miyabe ex Yamada)的重寄生菌(Tuberculina vinosa Sacc.)在垂丝海棠锈菌(Gymnosporangium yamadai Miyabe)上的寄生形态、侵入及控病作用作了报道。重寄生菌在垂丝海棠锈菌的性子器及性子器相对的叶背面均可发生。它完成侵入所需的最短时间为7小时,潜育期8-9天。该菌重寄生率从4月下旬的23.3%,逐渐上升至6月中旬的90.9%。

Abstract: The hyperparasite Tuberculina vinosa on Gymnosporangium yamadai were studied. The results showed that Tuberculina vinosa was found on aecidia of Gymnosporangium Yamadai and the opposite side surface of Ieaves. Ir took at least seven hours for the hyperparasite accomplishment its infecting activity. The incubation period was 8-9 days. The rate of the hyperparasite from 23.3% in the last ten days of April to 90.9% during the middle days of June.

Key words: GYMNOSPORANGIUM YAMADAI, TUBERCULINA VINOSA, MALUS HALLIANA
