Introduction Many species of dipterocarps are emergence trees and are classified as shade tolerance species. Their seeds normally germinate under the canopy shade and their seedlings could stay ‘dormant’ in the seedling bank while waiting for a gap to be created. Low light condition (1-5% sunlight), with high proportions of long-wavelength red and infrared light, is insufficient to sustain the seedling growth and development. Thus, the availability of gaps is critical for the … [Read more...]
