چکیده
ABSTRACT Organic residue in the substrate and availability of light influence production high-quality seedlings for ex situ cultivation native forest species. This study aimed to evaluate effect doses chicken manure incorporated soil shading levels on morphophysiological responses quality Alibertia edulis (Rich.) A. Rich seedlings. Five (CM) were tested, 0.00, 2.08, 4.16, 6.24, 8.32 g CM kg-1 soil, under two shade conditions, 0% (full sun) 50% shading. At 215 days after transplanting, maximum height obtained was 47.35 cm with 5.64 shade. Shaded had a higher number leaves. The leaf root areas 796.64 118.83 cm2 5.32 4.21 respectively, both Seedlings lower physiological indices. Shading did not affect stomatal limitation, but contributed efficiency. Shoot biomass doses. highest indexes occurred 3.98 6.28 0 shade, respectively. responded positively addition presented plasticity contrasting conditions. produced 6.24 high seedling indicators. 4.32 full sun
