Pomegranate (Punica granatum L.) disease incited by Coniella granati (Saccardo) has been recently reported in Tunisia causing branch dieback, shoot blight and fruit rot. The present study was undertaken in order to evaluate the response of nine known and widely grown pomegranate cultivars throughout Tunisia toward this emergent pathogen, to study the host range of C. granati and to identify its extracellular cell wall degrading enzymes. Plant response was determined based on fruit lesion diameter and length of external, internal and pycnidia-bearing lesions recorded on wounded and detached branches. All cultivars tested were susceptible to C. granati fruit rot where the lowest lesion diameters (87-88 mm), recorded 9 days post-inoculation (DPI), were noted on cultivars Gabsi and Zaghouani. At 30 DPI, intact detached branches were shown to be moderate.. View More»
