abstract = {By means of meta‐analyses we determined how 70 traits
related to plant anatomy, morphology, chemistry, physiology,
growth and reproduction are affected by daily light integral
(DLI; mol photons m−2 d−1). A large database including
500 experiments with 760 plant species enabled us to
determine generalized dose–response curves. Many traits
increase with DLI in a saturating fashion. Some showed a
more than 10‐fold increase over the DLI range of 1–50
mol m−2 d−1, such as the number of seeds produced per
plant and the actual rate of photosynthesis. Strong
decreases with DLI (up to three‐fold) were observed for
leaf area ratio and leaf payback time. Plasticity
differences among species groups were generally small
compared with the overall responses to DLI. However, for a
number of traits, including photosynthetic capacity and
realized growth, we found woody and shade‐tolerant species
to have lower plasticity. We further conclude that the
direction and degree of trait changes adheres with responses
to plant density and to vertical light gradients within
plant canopies. This synthesis provides a strong
quantitative basis for understanding plant acclimation to
light, from molecular to whole plant responses, but also
identifies the variables that currently form weak spots in
our knowledge, such as respiration and reproductive
characteristics.},
