Abstract
Native strains of Trichoderma viridae (CIAD 01-570903 and CIAD 03-580903), T. harzianum (CIAD 04-560903 and CIAD 05-550903), and T. lignorum (CIAD 02-590903 and CIAD 06-540903) showed inhibition in vitro against F. oxysporum, S. rolfsii, and R. solani. The chitinase activity and the inhibition of fungal pathogens by the Trichoderma strains presented a Pearson's correlation r = 0.90 for S. rolfsii inhibition. T. lignorum (CIAD 06 540903) was grown under simulated mycoparasitism with F. oxysporum, S. rolfsii or R. solani cell walls or glucose used as a carbon source. T. lígnorum showed a differential induction of chitinase and â-1,3-glucanase activity when grown with cell walls of R. solani, suggesting possible roles for these enzymes in pathogen cell wall lysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
