Other claims from this paper (7)
- Intervention effect Exposure of urediospores to 30 °C gave poor germination and damaged the spores.
- Observation Urediospores of broad bean rust germinated fastest at 20 °C within 5–26 °C.
- Observation Infection of Vicia faba leaves depended on a moisture film.
- Intervention effect Longer leaf wetness periods up to 24 h increased infection at 20 °C compared with 4 h.
- Intervention effect Lower temperatures slowed infection and reduced final pustule numbers.
- Intervention effect Daylight delayed spore germination.
- Intervention effect Higher light intensities increased the delay of spore germination.
