Other claims from this paper (7)
- Association Root to shoot ratio declined as nutrient level rose at both CO2 levels.
- Intervention effect High CO2 increased total seed weight relative to low CO2 at similar nutrition.
- Intervention effect High CO2 increased seed number relative to low CO2 at similar nutrition.
- Association At low CO2, seed weight rose with nutrient concentration through half strength, then fell at full strength.
- Association At low CO2, seed number rose with nutrient concentration through half strength, then fell at full strength.
- Intervention effect At high CO2, increasing nutrition from half to full strength did not significantly reduce seed weight and number.
- Intervention effect Elevated CO2 gave larger increases in dry weight between harvests as plants aged.
