Shading as a conditioning factor to forest species planting: a study with Apuleia leiocarpa

This study aimed at identifying the most appropriate level of shading for initial growth of Apuleia leiocarpa seedlings, through their survival, morphological and physiological/biochemical parameters. The following treatments were evaluated: 0 (full sun), 18, 50 and 70 % of shading. Survival was ass...
