Resumen o descripción
Phytophthora capsici is an oomycete known as the causal agent of wilting
disease in Capsicum spp., which causes rotting of roots, crowns, stems,
leaves and fruits. To date, little is known about the production of phytotoxic
metabolites by P. capsici or their role in the infection process. As part
of a project directed towards the isolation and identification of phytotoxins
produced by a strain of P. capsici pathogenic to habanero pepper (Capsicum
chinense), we have evaluated the effect of factors such as aeration,
light and culture medium on the production of mycelium and phytotoxic
metabolites by P. capsici. The results showed that culturing P. capsici in
potato dextrose broth (PDB) containing habanero pepper leaf infusion, in
the dark and under still conditions, results in a high production of mycelium
and a high phytotoxicity of the culture filtrate, in the shortest period
of time.
