Morphological Characterization of Corynespora cassiicola Isolates in Culture Media

Corynespora cassiicola threatens soybean and cotton production in Brazil. The objective of this study was to evaluate cultural morphological aspects C. isolated from different Brazilian regions, culture media. isolates were grown PDA (Potato Dextrose Agar) V8 juice agar characteristics evaluated were: color, aspect, growth rate mycelia, as well dimension conidia, number septa per conidium. Culture media compared using the Kruskal-Wallis or Tukey’s test at 5% significance level. mycelia predominantly dark gray light brown. grew better medium, presenting a higher mycelial rate. In conidia cotton, with isolates. There great variation regardless host origin. Conidia length width varied for isolate medium. coming presented conidium when vary depending on origin
