Fig Endosepsis in Some Cultivated Varieties

摘要

This work was conducted in 2000-2001 on 10 varieties of edible figs in the Erbeyli Fig Research Institute (EFRI) of the Aydin province to determine the incidence of fig endosepsis caused by Fusarium spp. A total of 284 Fusarium spp. were isolated from 30 figs randomly collected from each of 10 cultivars. One hundred ninety-six pathogenic Fusarium isolates were identified as Fusarium verticillioides (formerly Fusarium moniliforme) and 48 as Fusarium solani. The percentage of virulent and highly virulent isolates was 11.7 and 41.3 for F. verticillioides, 22.9 and 29.2 for F. solani, respectively. Regardless of cultivars, the relative virulence of F. solani isolates was found to be significantly higher than that of F. verticillioides. Two year studies showed that the incidence of pathogenic Fusarium isolates in fig cultivars was 19.7% in Bursa Siyah#l, 15.2% in Sultan Selim, 13.5% in Morgcoz, 12.7% in Beyaz Orak, 9.8% in Siyah #ncir, 9% in Ye?ilgcoz, 7.4% in Sar#l Lop (Syn. Calimyrna), 5.7% in Siyah Orak, 4.5% in Horasan and 2.5% in Sar#l Zeybek.
