Olpidium brassicae in cabbage roots

  • S. L. Singh
  • M. S. Pavgi


Morphology and development of the vegetative, asexual and sexual cycle Olpidium brassicae (Woronin) Dangeard parasitic in the roots of cabbage (Brassica oleracea L. var. capitata) seedlings was studied in detail. Release of zoo-spores through an exit tube from zoosporangia, their motility and encystment on the epidermal cells and root hairs, process of infection/host entry and later thallus development were described. Motility and fusion of 2 planogametes resulting in zygote formation were observed in slide cultures and described. The process of infection by zygotes and developmental stages of resting sporangia were also studied and described.
