The aim of this study was to investigate the responses linked to growth and morphological and anatomical changes in young plants of Parkia gigantocarpa subjected to waterlogging conditions. The experimental design was completely randomized with two water conditions (control and waterlogging) combined with five evaluation times (0, 4, 8, 12 and 16-days waterlogging conditions). The parameters evaluated were leaf specific hydraulic conductance, plant height, stem diameter, numbers of leaf and leaflets, as well as shoot dry matter, root dry matter, and total dry matter. The data were subjected to an analysis of variance, and significant differences between the means were determined using the F-test at a probability level of 5 %. Additionally, transversal sections linked to primary and secondary roots were described. The segments from the primary root (removed from region located 4 cm below of the soil surface) and the secondary root (removed from region located 4 cm from the root apex) were fixed, stained and mounted, and subsequently photo-documented. The waterlogging provoked reduction in leaf specific hydraulic conductance, as well as negative interferences on growth. Anatomically, this stress induced the appearance of hypertrophic lenticels in base of the stem, adventitious root and formation of schizogenous aerenchyma located in cortical parenchyma of the secondary root. Therefore, these results reveal the susceptibility of young Parkia gigantocarpa plants subjected to waterlogging conditions.
