Mendgen, Kurt Gold, Randall E. The effects of light and host volatiles on teliospore germination in Uromyces appendiculatus var. appendiculatus were studied.<br />1. Light intensities ranging 15-26000 lux supported teliospore germination and basidiospore formation. The optimum light intensity was 17000 lux under the described conditions. Light-dark alternation was necessary for teliospore germination: no germination occurred under continuous light or continuous dark conditions. The process of teliospore germination, basidiospore formation, and basidiospore release followed a synchronous, rhythmic pattern of development. Teliospore germination was triggered by the phase change light --> dark (i.e. "light off"). Under long-day conditions basidiospore release exhibited a nocturnal periodicity with peak maxima occurring ~ 7 h after light was turned off.<br />2. Fifteen days after a 10 d exposure to host volatiles, 70-80 % of the treated spores germinated; minor increases in spore mortality were observed. Inoculations made with seedling-treated teliospores resulted in heavy pycnial infections.<br />3. The heat and seedling activation methods developed for teliospores of bean rust proved ineffective when applied to dormant teliospores from six other unrelated rust species. application/pdf eng deposit-license 1983 Activation of Teliospore Germination in Uromyces appendiculatus var. appendiculatus.
