Ontogenetic variation in light interception, self-shading and biomass distribution of seedlings of the conifer Araucaria araucana (Molina) K. Koch Variación ontogenética en la intercepción lumínica, autosombramiento y distribución de biomasa en plántulas de la conífera Araucaria araucana (Molina) K. Koch

Revista Chilena de Historia Natural, 2006
One of the factors thought to contribute to ontogenetic declines in plant growth rates is diminishing light interception efficiency, as a result of the difficulties of avoiding self-shading among a growing number of leaves, and by stems.
