Aranda et al. (2006)

Leaf biomass of well watered and fertilized two-year-old seedlings grown for four months in controlled environment chambers in ambient and CO2-enriched air, after which they had all biomass above the point of attachment of the cotyledons to their stems removed from them, after which they were grown under the same conditions for four additional months, after which the leaf biomass that was subsequently produced was excised, dried and weighed
36%
