Fusarium oxysporum and F. solani, causal agents of wilt and rot root in citrus
seedling are variable pathogens. This study was conducted on the effect of different media
in characters, sporulation, and spore germination of fusarium spp. Isolates th
at were
isolated from seed and seedling of citrus.
The data revealed that the maximum mycelial growth was obtained in most isolates
on Potato Sucrose agar for F. oxysporum and F. solani, followed by Potato Dextrose agar
for F. oxysporum, and by Czapek’sDox agar for F. solani. The maximum sporulation was
recorded in Potato Sucrose agar medium followed byCzapek’sDox agar .
The study also showed that Potato Dextrose agar was the best for germination of
spores.
