Seedling establishment, growth, and survival depend on access to light, water, and nutrients. Across dipterocarp species there are a wide range of responses to light and, consequently, relative growth rates. This chapter explores this range, from species that are highly shade tolerant, to those that are more light demanding. The morphological and ecophysiological adaptations that underlie dipterocarp growth strategies under different light conditions are explored, as are the associated trade-offs. Tree form and architecture is important in this respect, and is associated with growth responses to light and wood density. Other associated traits include leaf structure, leaf area ratio, nutrient content, and resource allocation. Light acclimation responses are also important in determining how species respond to sunflecks and, in the longer term, to canopy gaps. Sudden exposure to high light environments provide growth opportunities, but also incur physiological stresses to which dipterocarp species are differentially adapted.
