Other claims from this paper (16)
- Observation Intercellular hyphae formed uredia that released urediniospores eight days after inoculation.
- Observation Resistant daylily cultivars had rapid host-cell death and three lesion and sporulation categories.
- Observation Prairie Blue Eyes had no visible disease symptoms but a few microscopically collapsed cells.
- Observation Bertie Ferris had no visible disease symptoms but a few microscopically collapsed cells.
- Observation Resistant and moderately resistant reactions showed necrotic lesions with many collapsed cells.
- Observation Chicago Apache produced uredia and urediniospores.
- Observation Buttered Popcorn did not produce observed uredia or urediniospores.
- Observation Stella De Oro did not produce observed uredia or urediniospores.
- Observation Susceptible cultivars lacked a hypersensitive response and fell into two categories of hyphal-growth restriction.
- Observation Mary Todd had a delayed latent period and reduced sporulation relative to Pardon Me.
- Observation Mary Todd had reduced sporulation relative to Pardon Me.
- Observation Chorus Line had a delayed latent period relative to Pardon Me.
- Observation Chorus Line had reduced sporulation relative to Pardon Me.
- Mechanism Hypersensitive cell death is a daylily rust resistance response.
- Association Leaf necrotic lesions were associated with the number of collapsed host cells.
- Mechanism Restricted hyphal growth causing delayed latency and reduced sporulation could be another resistance response.
