Other claims from this paper (13)
- Observation Attempts to infect host tissue cultures with urediospores failed.
- Observation Snapdragon cultures produced extracellular material inhibiting urediospore germination.
- Observation The inhibitory material could be leached in agar or water.
- Observation Rust mycelium failed to invade proliferating sunflower and red-cedar host tissues.
- Observation Some sunflower hypocotyl explants proliferated and produced roots, leaves and flowers on defined medium.
- Observation Leaf callus was isolated from shoots developed in vitro.
- Observation Sunflower leaf cultures and shoots could not be infected with Puccinia helianthi urediospores.
- Observation Infected snapdragon culture developed aerial P. antirrhini mycelium.
- Observation Aerial mycelium formed white tufts 1-3 mm long.
- Observation Transferred mycelium did not continue growth on nutrient medium.
- Observation The mycelium could not infect host tissue cultures.
- Intervention effect Urediospore inoculation of epidermis covered snapdragon cultures did not produce infection.
- Observation Contact with germinated urediospores failed to infect callus.
