PHYSIOLOGICAL AND MORPHOLOGICAL VARIABILI TY OF COLLETOTRICHUM-GUARANICOLA IN DIFFERENT SUBSTRATES

The physiological and morphological of nine isolates of Colletotrichum guaranicola were studied. For the physiological characterization four culture media (PDA, oat, bean and earn) were used under continuous li ght regime at 25 degrees C, during seven days. The corn medium promote d higher mycelial growth and the oat medium induced higher sporulation of most isolates. The morphological characterization showed variation among the isolates. The isolates ISO-1 and ISO-2, ISO-8 and ISO-9 wer e similar to each other in relation to cultural and morphological char acteristics.
