| Resumo: |
The ability of Verticillium lecanii (Lecanicillium muscarium; B-2) to induce host resistance and defense responses against subsequent challenge with cucumber powdery mildews was examined in a glasshouse. A root test showed that, after inoculation with V. lecanii blastspore on cucumber roots, induction of systemic resistance in those V. lecanii pre-inoculated plants engendered significantly fewer lesions and reduced disease severity compared with non-inoculated plants. Furthermore, in plants inoculated with V. lecanii blastspore on their roots, the fungi showed high colonizing ability on cucumber rhizoplane and inside root tissues. Nevertheless, activities of peroxidase (PO) and phenylalanine ammonia-lyase (PAL) increased slightly, but not significantly. In a leaf test of inoculation with V. lecanii, activity of PAL tended to increase when powdery mildew was inoculated, but the PO activity did not change significantly. These results indicated that an isolate of V. lecanii (B-2) potentially induced host resistance to cucumber and is an effective candidate for biological control of cucumber powdery mildews, even in inoculation into soil.
