摘  要:
苹果轮纹病菌(Physalospora piricola)是黄河故道地区苹果(Malus sp.)树主要病害之一。近年来,该病的发生与危害日趋严重,给苹果生产造成了很大的损失,严重影响了苹果的质量和产量。苹果轮纹菌不仅侵染田间生长的苹果,由于其潜伏侵染特

摘  要:
The antifungal action and potential mechanism of pyrolin against Physalospora piricola were studied. The results showed that Physalospora rot of apples could be significantly suppressed by Pyrolin,and the MIC value was 0. 156 mg·mL -1 and MFC value was 0. 313 mg·mL -1. The activities of PPO and PAL in apples increased significantly on inoculation with Pyrolin and a pathogen,P. piricola or the pathogen alone,and maintained at a high level throughout the experiment. Moreover,fruits inoculated with Pyrolin + P. piricola or P. piricola alone also stimulated POD activity. The observations with SEM revealed that hyphae distorted,the mycelium adhered,substance of flocculent agglutination occurred on cell surface. The observations with TEM showed that the hypha cell inner structure was disordered and damaged severely.
