Fig. 6. Dry weight of plantlets from distal and proximal halves of the paracladial zone following the cessation of culm elongation growth in Poa alpina. Plants were grown at either 350 µmol mol^–1 (ambient) or 690 µmol mol^–1 (elevated) atmospheric CO₂, and two nutrient regimes: one‐fifth strength (low nutrient) or full‐strength (high nutrient) Long Ashton nutrient solution. Data are means of four replicates ± s.e.
