Other claims from this paper (8)
- Intervention effect Joint pathogen infection significantly reduced potato carbon assimilation at 42 days but not 16 days.
- Intervention effect Joint pathogen infection significantly reduced potato leaf light use efficiency at 42 days but not 16 days.
- Intervention effect Joint pathogen infection increased intercellular carbon dioxide in potato leaves at 42 days but not 16 days.
- Intervention effect Infection by either pathogen alone had little or no effect on potato leaf gas exchange parameters.
- Intervention effect Either single pathogen treatment did not change the initial slope of the potato assimilation versus intercellular CO2 curve at 16 days.
- Intervention effect Joint infection significantly reduced the initial slope of potato assimilation versus intercellular CO2 curves at 42 days.
- Mechanism The authors suggest nonstomatal effects could explain reduced potato carbon assimilation during late joint infection.
- Mechanism The authors suggest leaf patchiness may contribute to reduced photosynthesis in jointly infected potato leaves.
