Accumulation of phytoalexins in leaves of plane tree (Platanus spp.) expressing susceptibility or resistance to Ceratocystis fimbriata f.sp. platani.

1995-09-01

Abstract excerpt

Inoculation of leaves of resistantPlatanus occidentalis and susceptiblePlatanus acerifolia leaves withCeratocystis fimbriata f. sp.platani, the canker stain disease agent, induced foliar necrosis and biosynthesis of two phytoalexins, scopoletin and umbelliferone. Foliar symptoms keep localized and accumulation of coumarin phytoalexins was rapid for incompatible interactions. Necrosis spread widely and accumulation...
