Resumo: 	ABSTRACT Garcinia madruno (Kunth) Hammel is a neotropical tree that naturally occurs in terra firme forests and is important as a source of income and medicine for Amazonian populations. This study describes and compares the morphoanatomical responses of plants under conditions of stress and normoxia. Young plants of Garcinia madruno were subjected to two water regimes: daily controlled irrigation and waterlogged for 84 days. Hypertrophic lenticels, adventitious roots and anatomical characteristics of the roots and leaves were evaluated on days 0, 21, 42, 63 and 84. There were no changes in leaf structure, but cracks and hypertrophic lenticels appeared on the stems, there was an increase in blackness of the roots and the plants formed adventitious roots to adapt to the flooded environment. The anatomical changes in the roots of the flooded plants were thickening of the exodermis in the main root and of the pericycle in the lateral roots, and a large increase in the amount of aerenchyma. Histochemical tests detected starch in the midrib, mesophyll, stem and root of flooded plants, and in the petiole of control plants. In the waterlogged plants, phenolic compounds were found in the petiole and alkaloids were found in the midrib, petiole and root.
