The energy conversion efficiencies (ε) of a fictional plant stand producing 2500 g total DW m−2 during a growth cycle of 100 days. Calculations are based on the pessimistic approach (PA), and stepwise changes in parameters listed in Table 1 under the optimistic approach (OA), or with all parameters changed according to the OA scenario (a, b: quantum requirements, Φ: the ratio of oxygenation to carboxylation, fabs: the fraction of light absorbed by leaves)
