Abstract:

The elapsed time between inoculation of a Ribes leaf with urediniospores and the production of teliospores by Cronartium ribicola J. C. Fisch. ex Rabenh. was shortened by reducing postinfection incubation temperatures and by using host plants that had dormant buds. The effect of temperature was relatively small, but that of dormancy was large; this suggests that factors responsible for teliospore induction were related to changes in the physiological status of host tissues. Forest Sci. 18:321-323.
