Screening and Identification of Spoilage Moulds from Postharvest Sweet Cherry in Yantai
In order to clarify the dominant mould species causing postharvest decay of sweet cherry in Yantai,spoilage moulds from decayed sweet cherry fruits were screened and identified by internal transcribed spacer (ITS) sequence analysis.Typical strains were examined for colonial morphology and then re-inoculated into sweet cherry to test their pathogenicity.A total of 60 moulds were isolated from decayed sweet cherry from different regions of Yantai,and they were assigned to 6 species based on both ITS sequence analysis and morphological identification,Mucor racemosu,Fusarium tricinctum,Alternaria alternate,Penicillium polonicum and Aspergillus fumigatus.The predominant species were Alternaria alternate (14 strains) and Mucor racemosu (15 strains).Compared with naturally decayed sweet cherry,sweet cherries inoculated with moulds were decayed and displayed the same colonial morphology.
