Induced resistance of Hevea to South American leaf blight by incompatible races of Microcyclus ulei
Material type:
TextPublication details: Journal of Natural Rubber Research 1986Description: 195-201Subject(s): Summary: Inoculation of leaf discs of Hevea by an isolate of Microcyclus ulei incompatible to a Hevea clone induced resistance to subsequent infection by a compatible race. Simultaneous inoculation of compatible and incompatible races reduced the size of lesions but not their numbers. Inoculation of an incomparable race 24 h prior to inoculation of a compatible race induced both the number and size of lesions. The reduction was proportional to the concentration of the incompatible race inoculum. On intact leaves, inoculation of a compatible race prior to an incompatible race reduced the number of lesions and the conidia produced.
