Other claims from this paper (7)
- Observation Only three tropical Pythium isolates (one P. ultimum and two P. aphanidermatum) were pathogenic to tropical tree species.
- Observation Tropical pathogenic isolates were pathogenic on 4-6 of eight tree species.
- Observation Temperate Pythium isolates were pathogenic on 0-4 of eight tropical tree species.
- Observation Two of the eight tropical tree species were not susceptible to any Pythium isolate.
- Observation Pythium isolates varied widely in pathogenicity, causing differential mortality of potential host species.
- Observation The tree species varied in their susceptibility to a given Pythium isolate.
- Mechanism The authors interpret the differences in pathogenicity and susceptibility as some support for the Janzen-Connell assumption of host specificity.
