Abstract
Germination of surface-disinfected resting spores ofPlasmodiophora brassicae and its infection of turnip hairy root hairs were studied. Surface-disinfected resting spores showed higher germination than non-disinfected resting spores. Root hair infection was most frequent in the section of root formed 1 d before inoculation. Root hair infection began 4 d after inoculation, increased up to 6 d, and continued to increase more slowly until 10 to 12 d after inoculation. Growth ofP. brassicae in the root hair of hairy roots was observed serially. Most primary plasmodia differentiated to mature zoosporangia 8–10 d after inoculation. The secondary zoospores were initially released 6 d after inoculation.
