Scanning electron microscopy (SEM) micrographs showing the pattern of colonization by A. terreus phialidic conidia on potato cv. Kufri Jyoti leaf. (A) Phialidic conidia produced multipolar germ tubes by 8 h after inoculation, imaged at 3000X. (B) Differentiation of germ tubes into irregular protuberance (indicated by arrows) by 24 h after inoculation, imaged at 5000X.
