ABSTRACT
This study was designed to ascertain the different types of fungal flora that are associated with spoilage of citrus fruits such as lime, lemon and sweet orange after harvesting the fruits. Fungi were isolated from the spoilage fruits under using standard laboratory techniques and appropriate media. Pure cultures of the isolates were obtained, colonial and morphological characteristics of the isolates identified based on the morphological and microscopic characteristic. The study revealed that several species of fungi were found to be associated with the spoilage of different types of citrus fruits. However, the most predominant fungi isolated were Aspergillus niger with (25.90%) in lime, (21.5%) in lemon and (23.38%) sweet lemon. However, a total number of 286 fungi were isolated with (40.56%) fungi in lime, followed by lemon with (32.52%) and the least is sweet lemon with (26.92%). The pathogenicity test revealed that the healthy citrus fruits injected with isolated fungi from spoiled citrus fruits shows similar growth characteristics to the original diseased sample and the result showed that Aspergillus niger has the highest diameter zone of spoilage, with 15.5mm in fresh lime, 14.5mm in fresh lemon and 5.0mm in sweet orange. Proper agricultural and handling practices can reduce the effects.
