Other claims from this paper (10)
- Intervention effect Fluorescent light or sunlight for 2 or 4 h significantly reduced germination and germ tube elongation of Puccinia hemerocallidis urediniospores on detached daylily leaves.
- Intervention effect Fluorescent light for 2 or 4 h significantly reduced germination of Puccinia pelargoniizonalis urediniospores on detached geranium leaves.
- Intervention effect A 4 h exposure to either light source significantly reduced lesion development of Puccinia hemerocallidis on detached daylily leaves.
- Intervention effect Hydrated urediniospores of Puccinia hemerocallidis produced fewer lesions on detached daylily leaves than dry urediniospores.
- Intervention effect Sunlight for 1 h (hydrated) or 2 h (dry) significantly reduced lesion development of Puccinia hemerocallidis on whole daylily plants.
- Intervention effect Sunlight for 1 h (hydrated) or 2 h (dry) significantly reduced lesion development of Puccinia pelargoniizonalis on whole geranium plants.
- Intervention effect Increasing fluorescent light exposure negatively affected sporulation of Puccinia hemerocallidis on daylily.
- Intervention effect Increasing fluorescent light exposure negatively affected sporulation of Puccinia pelargoniizonalis on geranium.
- Intervention effect Complete suppression of sporulation was not observed for either rust with up to a 24 h exposure to fluorescent light.
- Recommendation Exposure to high light intensities may affect the spread of rust diseases on ornamental plants.
