Fungi associated with dieback of pomegranate (Punica granatum L.) in Dalmatia
Pomegranate is a fruit species of high value which is traditionally grown as a fruit or ornamental tree in gardens in the Croatian coastal area and has a large unused potential for commercial cultivation. It is susceptible to a number of phytopathogenic fungi that cause various diseases, with fruit, and more recently wood diseases, being considered as most important. Symptoms of pomegranate wood diseases include scarring of bark, wood necrosis, cankers, chlorotic leaves, dieback of shoots, branches and whole trees, while fungi from genera Ceratocystis, Coniella and Cytospora are reported as possible causal agents. During 2017, these symptoms were observed on several sites in Dalmatia, so the aim of this study was to determine a link between observed symptoms and phytopathogenic fungi. Wood samples from symptomatic plants of different varieties were collected from which fungi were isolated on PDA media and tentatively identified on the basis of morphology. Part of the isolates were further identified based on analysis of molecular markers ITS and EF1-α. In all analyzed samples, the presence of fungus Cytospora punicae, a known cause of dieback of pomegranate, was determined, while Penicillium sp. and Alternaria sp. were present in small number of samples. It is concluded that C. punicae is a probable cause of pomegranate dieback in Dalmatia, which will have to be further tested by pathogenicity trials. This is the first report of C. punicae on pomegranate in Croatia.
