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