Abstract

In coculturing with strains of Trichoderma and oyster mushroom, we could detect the difference in the resistance of oyster mushroom against Trichoderma with the phenomena of barrage reaction, overgrowth and lysis. We selected the isolates ASI 2183, ASI2504 and ASI 2477 as varieties that showed the resistance. The isolates ASI 2240, ASI 2479 and ASI 2181 were the best in their resistance against Trichoderma in the method using culture filtrate. In common, the isolates ASI 2479 and ASI 2240 were selected in both methods. In post-inoculation method, the isolates ASI 2479, ASI 2333 and ASI 2181 were selected and ASI 2302 was susceptible. For the same isolate of Trichoderma, the resistance varied depending on the isolates of oyster mushroom used in the experiments. Because we could detect the interactions between Trichoderma and oyster mushroom, it is possible to detect the level of the resistance that differs in the varieties. However, there were the cases of detecting the level of the resistance in repetitions with the same isolate, which may be caused by the vitality of isolates of Trichoderma and oyster mushroom. It is efficient to test the resistance with the resistant isolate of Pleurotus salmoneostramine and the susceptible isolate of ASI 2302.
