Isolation,identification and pathogenicity of fungi on the surface of pomegranate fruit
[Objective]To preliminarily explore the fungal species on the surface of Kashgar pomegranate fruits and test their pathogenic ability.This finding has provided data reference for the prevention and control of fungal diseases in pomegranate fruit in Xinjiang.[Methods]The fungi on the surface of pomegranate fruit were isolated,purified,identified and classified by morphology and molecular biology,and then the pathogenici-ty of fungi to pomegranate fruit was determined by puncture inoculation test.[Results]Seven different fungi were isolated and identified,among which,the following four could obviously cause pomegranate fruit rot.Both of Aspergillus luchuensis and Penicillium italicum showed higher infection ability to pomegranate peel and grain;Alternaria eichhorniae only had higher infection ability to pomegranate pulp;Penicillium adametzioid had wea-ker infection ability to pomegranate peel and grain.In addition,Talaromyes rubrifaciens,Cladosporium antarcti-ca and Amorphotheca resinae did not show obvious pathogenicity to peel and grain.[Conclusion]The main pathogenic bacteria of pomegranate fruit under the ecological conditions in southern Xinjiang are different from those in other suitable growing habitats in China.
