Abstract: |
Every year, date fruits stored in cold storage suffer significant damage from various factors. Among these factors, storage pests and post-harvest diseases are particularly detrimental to the quality of date fruits. It is crucial to monitor and detect these pests and diseases early on in order to prevent and manage outbreaks in post-harvest conditions. In order to assess the presence of fungal agents, five samples weighing one kilogram each were randomly collected from each cold storage every two weeks (ten cold storages). These samples were then transported to the plant protection research laboratory of Baluchestan Agriculture and Natural Resources Research and Education Center. After sampling, infected samples were cultured on general and special culture media to identify pathogenic agents. Pure culture of fungi was prepared using the single spore method and threading in potato-dextrose-agar (PDA) food medium. A total of 114 isolates from the fungal genera Penicillium, Aspergillus, and Alternaria were isolated and identified by morphological criteria. Subsequently, twelve isolates with distinct morphological characteristics were chosen for DNA extraction and determination of nucleotide synonyms.
