Other claims from this paper (19)
- Intervention effect Infection increased leaf and stem dry weight.
- Intervention effect Infection slightly decreased root and stolon dry weight.
- Intervention effect Nitrogenous fertilizer reduced virus-related tuber dry weight loss.
- Intervention effect Phosphorus and potassium did not affect virus-related tuber loss.
- Intervention effect Infection decreased net assimilation rate through early July.
- Observation Infected plants had higher later net assimilation rate.
- Intervention effect Infection decreased leaf area until early July.
- Intervention effect Infection delayed leaf senescence and increased late leaf area.
- Observation Mean infection-related net assimilation rate decrease was about 20%.
- Observation Mean infection-related leaf area decrease was 4%.
- Mechanism Older rolled leaves had diminished photosynthetic efficiency underlying lower net assimilation.
- Observation Nutrient effects on net assimilation and interactions with infection were small and rarely significant.
- Intervention effect Nitrogenous fertilizer increased leaf area throughout growth.
- Intervention effect Phosphorus increased early leaf area.
- Intervention effect Phosphorus hastened senescence and decreased August leaf area.
- Intervention effect Potassium increased leaf area particularly later in growth.
- Observation Infected plants had more leaves than healthy plants beyond early growth.
- Intervention effect Shading decreased net assimilation rate and increased leaf area without affecting yield.
- Observation Virus-related yield loss was smaller in Up-to-Date than Craig’s Defiance.
