Other claims from this paper (8)
- Intervention effect N fertilizer increased soluble N up to 19 times control values.
- Intervention effect Total N in one-year foliage, current twigs and roots differed across N treatments.
- Intervention effect Guanidino compounds in one-year twigs differed across N treatments.
- Association Six N measurements explained 60% of variance in plant size.
- Intervention effect Soluble N compounds were higher at 21 °C than 10 °C.
- Intervention effect Total N concentration was not higher at 21 °C than 10 °C.
- Intervention effect Moisture stress increased soluble N compounds, particularly proline.
- Observation Provenances differed in soluble N compound and total N concentrations.
