Abstract

We investigated some aspects of flooding tolerance in two riparian populations (exposed and no exposed to flooding) of Luehea divaricata C. Martius. Plants derived from seeds collected in each population were submitted to flooding (30 and 60 d), submergence and re-aeration treatments. Plants exposed to flooding showed development of aerenchyma, hypertrophic lenticels and new adventitious roots. Interestingly, whereas the plants originated from population naturally exposed to flooding developed some of these alterations more markedly, they could not survive when totally submerged. The random amplified polymorphic DNA (RAPD) markers, showed a significant difference between populations, suggesting that seasonal flooding on riparian populations of L. divaricata has been selecting individuals who are more adapted to survive in these conditions.
