Evidence of ecotypic differentiation between populations of the tree species Parapiptadenia rigida due to flooding

D. C. G. Silva, Carvalho, M. C. C. G., Ruas, P. M., Ruas, C. F., and Medri, M. E., Evidence of ecotypic differentiation between populations of the tree species Parapiptadenia rigida due to flooding, vol. 9, pp. 797-810, 2010.

The tree species Parapiptadenia rigida, native to southern South America, is frequently used in reforestation of riverbanks in Brazil. This tree is also a source of gums, tannins and essential oils, and it has some medicinal uses. We investigated flooding tolerance and genetic diversity in two populations of P. rigida; one of them was naturally exposed to flooding. Plants derived from seeds collected from each population were submitted to variable periods of experimental waterlogging and submergence.
