Claim · model-written summary
P. pustulans spore length was reduced on aerial tubers.
Verbatim
e0“Spore length of P . pustulans was reduced and spore width increased, while spore length and width of P . exigua var. foveata were reduced on aerial compared with subterranean tubers inoculated with these pathogens.”

Other claims from this paper (13)
- Intervention effect Pathogens cultured on aerial tuber powder had significantly reduced growth rates, spore numbers and conidiophore numbers.
- Intervention effect F. solani var. coeruleum spore size was unaffected in culture.
- Intervention effect Spore and conidiophore lengths of remaining pathogens were reduced in culture.
- Intervention effect Spore and conidiophore width of remaining pathogens increased in culture, with stated exceptions.
- Intervention effect Colletotrichum coccodes acervulus diameter increased in culture.
- Intervention effect P. exigua var. foveata spore length and width were reduced in culture.
- Intervention effect Aerial tubers inoculated in vivo had lower disease incidence, severity and spore numbers than subterranean tubers.
- Intervention effect P. pustulans spore width increased on aerial tubers.
- Intervention effect P. exigua var. foveata spore length and width were reduced on aerial tubers.
- Intervention effect Fusarium spp. spore size was unaffected in vivo.
- Observation Aerial tuber tissue had higher glycoalkaloid, chlorogenic acid and calcium concentrations.
- Observation Aerial tuber tissue had higher magnesium concentrations.
- Mechanism Higher aerial tuber chemical concentrations may contribute to resistance and fungal spore morphology effects.
