dc.descriptionProducts that have biostimulant action on forest seedlings, such as those based seaweed Acadian® and hormones, have been used due to their beneficial effect on the physiology and growth of plants, in order to improve the quality of forest seedlings. The present study establishes as research problem: Can doses of Acadian® algae extract and Stimulate® be effective for the initial growth and physiological indices of jatobá seedlings? The variables evaluated were: shoot height (H), stem diameter (SD), increments in stem diameter (ΔSD) and shoot height (ΔH), shoot dry mass (SDM, g plant-1), root dry mass (RDM, g plant-1) and total dry mass (TDM, g plant-1), and Dickson quality index, net assimilation rate (EA, g.m-2.day), leaf relative growth rate (RA, g.m-2. day), leaf area ratio (FA, m2.g-1), specific leaf area (SA, cm2.g-1), leaf mass ratio (Fw, g/g-1) as well as nitrogen balance index (NBI) and chlorophylls. The plant growth regulators (Acadian®) at the dose of maximum technical efficiency of 0.28 ml L-1 promotes an increase in stem diameter in Hymenaea courbaril. Acadian® increases chlorophyll a and b contents in Hymenaea courbaril seedlings. The tested doses of Stimulate® do not increase chlorophyll a and b contents in H. courbaril seedlings.
