Table 1. Vertical distribution of photosynthetic photon flux density (PPFD) in a secondary temperate rainforest of Southern Chile.

Values correspond to daily mean ± SE (n = 2). Measurements were carried out in January 2011 in the Katalapi Park.

Trunk height (m) Mean PPFD (μmol photons m-2 s-1) Absolute maximum PPFD (μmol photons m-2 s-1)
< 1 32 ± 2 501
4.5 89 ± 4 548
9 623 ± 15 1,738
