Other claims from this paper (19)

Intervention effect Virus infection decreased total dry weight mainly through tuber dry weight loss.
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 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.

Other claims from this paper (5)

Intervention effect Yield increased or decreased with seed-borne Fusarium, depending on the cultivar.
