The objective of this work was to evaluate the initial growth of Tabebuia serratifolia (Ipê Amarelo) seedlings under different water regimes, in order to find the one that best fits the species in the initial phase of growth. The following equipment was used to measure dendrometric variables, namely: digital caliper to measure DAC (Neck Height Diameter) and millimeter ruler to measure seedling height. The design used was a completely randomized design (DIC) where 6 replications were performed with 5 treatments in a total of 30 individuals, submitted to various water stress, and a control. It was concluded that the seeds of Ipê Amarelo have capacity to adapt to moderate water stress, presenting potential to be successfully used in some phases of degraded areas recovery; however, severe water deficit can affect the onset of germination and delay its development.
