- Intervention effect Nitrogen limitation reduced aboveground growth of Spartium junceum
- Intervention effect Supplemental soil nitrogen from NH 4 + increased growth of Spartium junceum
- Intervention effect Supplemental soil nitrogen from NH 4 + increased stem area more than leaf area
- Intervention effect Excess NH 4 + decreased growth of leaves and stems of Spartium junceum
- Observation Stems held a greater amount of nitrogen than leaves in Spartium junceum, particularly on a surface area basis
- Intervention effect Stem and leaf assimilation were reduced under limiting nitrogen
- Association Stem contribution to daily carbon gain increased compared with leaves
- Association Stem and leaf assimilation had similar linear relationships with tissue nitrogen concentration
- Intervention effect Nitrogen use efficiency increased under nitrogen limitation in Spartium junceum
