Morphological and cultural characteristics of Fusarium oxysporum f sp. gladioli

Abstract

In the present investigation on different media all the nine solid media tested exhibited better mycelial growth and sporulation of test pathogen. However the most suitable media were viz., Potato dextrose agar with maximum radial mycelial growth (9.12 cm). Followed by media Oat meal agar (6.97 cm) and Richard’s agar (6.90 cm). The minimum radial growth was obtained in Yeast dextrose agar (2.00 cm).Mycelium was whitish in most of media except in case of Potato dextrose agar, where mycelium was pink cottony and pluffy, whereas in case of Malt extract agar the mycelium was brownish white. Sporulation was abundant in Potato dextrose agar, Richard’s agar and Oat meal media.
