Stem uprighting in tree saplings

Tree saplings growing in a forest understorey undergo frequent changes in their light environment, to which they must adapt. Collet et al. analyse changes in sapling stem inclination over 4 years after canopy opening in Fagus sylvatica and Acer pseudoplatanus. Both species show considerable and rapid stem reorientation resulting in more erect shoots, and the results suggest that this process plays a significant role in the growth strategy of the species.
