Abstract
In face of the global situation, a practice which has been gaining strength is producing seedlings for environmental
restoration. Among the species that stand out for such activity is Hymenaea stigonocarpa. However, little is known
about their nutritional requirements. The objective of this study was to evaluate the morphophysiological behavior
of H. stigonocarpa seedlings submitted to phosphorus doses. The design was completely randomized with five doses
(0, 100, 200, 300 and 400 mg dm-³) and four replicates. Physiological, morphological, biomass and phosphorus
content analyses were performed. There was a difference for root mass ratio, leaf mass ratio, shoot mass ratio, leaf
area and root area. The dose of 200 mg dm-³ is recommended for H. stigonocarpa seedlings.
Keywords: physiological parameters, initial growth, jatobá do cerrado, allometric reasons.
