  • 1998). Nevertheless, the presence on 7-day-old PCA of Simmons and Roberts' sporulation pattern 6 and a restricted number of conidia (two to three) per sporulation unit, associated with primary conidia and long (over 7 μm) apical secondary conidiophores, are useful criteria to differentiate A. triticina isolates from some of the other nonpathogenic Alternaria species (Mercado-Vergnes et al.
