An experiment was carried out in order to study the morpho-anatomical responses of plants of Chorisia speciosa to flooding. Plants were maintained in well-drained and flooded soils for 45 days. The flooded plants grew less than the control and formed a great number of hypertrophied lenticels. Flooding caused death of part of the original roots and the remaining roots exhibited low regeneration capacity. The stem base of flooded plants showed a thicker cortex, narrower vessel members and a lower number of sclerenchyma bundles than the control. In the transition region of flooded plants hypertrophied lenticels, hair and root primordia were observed. Although vegetative growth was reduced in flooded plants, the species presented morpho-anatomical plasticity, which could contribute to its tolerance to flooding.
