Crown structure of a codominant Douglas-firCanadian Journal of Forest Research (1983)
Results are presented from an intensive study of crown structure in a 39-year-old codominant Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco). The patterns of crown development observed may represent a species adaptation for maximizing photosynthetic efficiency. While branches originating at nodes provide the basic structure of the crown, short-lived nonnodal branches provide much of the photosynthetic capacity. In addition, nonnodal branches support nearly half of the young needles near the top and outside edges of the crown.
