Original Title Effets d'un gradient de lumiere sur la croissance en hauteur et la morphologie de la cime du sapin baumier regenere naturellement. Source Canadian Journal of Forest Research. [Ottawa, National Research Council of Canada] June 1995. v. 25 (6) p. 878-885. Abbreviated Source Canadian Journal of Forest Research. June 1995. v. 25 (6) p. 878-885. ISSN 0045-5067. Coden CJFRAR. Note Includes references. Abstract This study characterized the height growth and crown form of 14-year-old balsam fir regenerated naturally under a light gradient varying from 3 to 83% of photosynthetic photon flux density (PPFD). After 14 years, total height growth was correlated with percent PPFD (R- = 0.766; p < 0.001). From 3 to 25% of PPFD, balsam firs went from a suppressed stage with an umbrella type crown shape to a full grown stage with a cone type crown shape. This morphological change was caused by a greater increase in leader length compared to the mean nodal branches length. The number of nodal and internodal branches increased with PPFD. Balsam fir crown morphology showed a strong plasticity with a light gradient going from 3 to 83% of PPFD.
