Other claims from this paper (6)
- Intervention effect Low nitrate decreased carbon assimilation by 30–35% in young and mature chicory.
- Intervention effect In young plants, nitrate supply did not modify the shoot/root carbon ratio or root enzyme activities.
- Intervention effect In mature plants, low nitrate decreased the shoot/root carbon ratio from 0.6 to 0.2.
- Observation Mature plants had greater SST activity than young plants at both nitrate levels.
- Intervention effect Mature low nitrate plants had twice the SST activity of mature high nitrate plants.
- Mechanism Authors attributed the lower shoot/root dry weight ratio at low nitrate to greater carbohydrate storage from elevated root SST activity.
