以经过热处理初加工葡萄果粒为样品,对其在贮藏期间发生腐烂的主要病原菌进行调查,并对病原菌进行分离、培养和回接试验,确定了腐烂病害的病原菌分别为青霉、链格孢、镰刀菌和葡萄孢,而且确定了病害为混合侵染。 The results showed that the main pathogenic bacteria which decayed during storage were investigated by heat treatment on the freshly harvested grape fruit samples. The pathogenic bacteria were isolated, cultured and returned to the test. The pathogenic bacteria of the rot disease were identified as Penicillium, Alternaria Fusarium and Botrytis cinerea, and the disease was identified as mixed infection.
