dc.description.abstractMyracrodruon urundeuva Fr. All. is a medicinal plant of the Caatinga biome, in brazilian northeast. This region is characterized by prolonged dry periods but little is known about the plants mechanisms to tolerate low water availability during their initial phase of growth and establishment seedling. The objective of this project was to evaluate morphological and anatomic characteristics of M. urundeuva seedlings submitted to different water levels in the soil. In a first experiment, the diaspores were sown in trays containing soil taken from the place of occurrence of the species. The substratum was moistened with water to reach 10 to 60% of the soil water retention capacity, with 5% intervals. In a second experiment, the diaspores were sown in the substratum kept at 60% of its water retention capacity for 15 days for the total seedling emergence since this is the most favorable condition for the species as identified during the first phase of this experiment. After that period, plant watering was suspended and the seedling kept in substrata at 60, 30, 25, 20, 15, and 10% of their water holding capacity for an additional period of 10 days, both experiments performed in protected environment. The increasing reduction in water availability led to a reduction in the number of leaves, the leaf area and leaflet thickness, the number of stomata in the leaf and in the cotyledon, the root length and the diameter of the central root. Characteristics such as the stem length, length, width and thickness of the cotyledon were not modified by the hydric stress.en
