摘要
本文对梨胶锈菌（ＧｙｍｎｏｓｐｏｒａｎｇｉｕｍａｓｉａｔｉｃｕｍＭｉｙａｂｅｅｘＹａｍａｄａ）的重寄生菌（ＴｕｂｅｒｃｕｌｉｎａｖｉｎｏｓａＳａｃ．）在垂丝海棠锈菌（ＧｙｍｎｏｓｐｏｒａｎｇｉｕｍｙａｍａｄａｉＭｉｙａｂｅ）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％。
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 leastseven hours for the hyperparasite accomplishment its infecting activity. The incubation period was 8-9 days. The rate of the hyperparasite from 23.3% in thelast ten days of April to 90.9% during the middle days of June.
