Abstract

We identified that in a two meter high greenhouse grown cucumber canopy, photosynthesis is mostly light-limited, and light interception and biochemical capacity are the major factors limiting photosynthesis. The diffusion pathways, stomatal and mesophyll conductance, are minor restrictions.
