| 实物特征: | This researchaimed to determine the relationship between the color of thepigment produced by isolates of F. verticilliodes and virulencein maize seedlings. Symptomatic and asymptomatic corn cobswere collected in Veracruz State, Mexico during the springsummercycle of 2008. The experiment was analyzed using anexperimental design in split plots with a double division, undergreenhouse conditions during two crop cycles, fall-winter of2008 and spring-summer of 2009, in the Postgraduate CollegeCampus Montecillo, Mexico State. The pigmentation of theisolates obtained from symptomatic seeds with mycelium wasmore intense with a purple color, and the white myceliumisolates showed a more homogeneous color. Isolates fromasymptomatic seeds had a tenuous violet coloration, and fromwhite to cream coloration of mycelium. It was observed thatisolates from symptomatic and asymptomatic seeds werepathogenic; the purple isolations from symptomatic seedswere more virulent than the white isolate, opposite to whathappened with the isolation from asymptomatic seeds, inwhich the white mycelium was more virulent. |
