Abstract
- Infection types were assessed when four cultivars of <em>Populus deltoides</em> Marsh, were inoculated with six races of <em>Melampsora medusae</em> Thüm, and incubated in combinations of light intensity (100, 500 and 1000 μEm-2s-1) and temperature ( 15 and 25 °C). Resistance in the cultivars was always at a maximum when the race/cultivar complexes were incubated in the high light intensity (1000 μEm-2s-1)/high temperature (25°C) regime. Increasing light intensity was generally associated with reduced infection type in the cultivars; the reduction was more pronounced in an incubation temperature of 25 than 15 °C. The potential epidemiological significance of the results is discussed. [ABSTRACT FROM AUTHOR]
