Abstract

DAVANSO-FABRO, Viviane M.; MEDRI, Moacyr E.; BIANCHINI, Edmilson  and  PIMENTA, José A.. Tolerância à inundação: aspectos da anatomia ecológica e do desenvolvimento de Sesbania virgata (Cav.) Pers. (Fabaceae). Braz. arch. biol. technol. [online]. 1998, vol.41, n.4, pp.475-482. ISSN 1516-8913.  http://dx.doi.org/10.1590/S1516-89131998000400012.

Twenty days seedlings of Sesbania virgata (Cav.) Pers. (Fabaceae) cultivated in green house were flooded by forty days. Flooded plants presented increasing of dry weight and lenght, evident cortical fissures and spongy cortical swelling on the stem basis and root, superficial roots on the soil and adventitious roots. It is possible that the morpho-anatomic plasticity presented by this specie is contribuiting for its hipoxic soils stablishment.

Keywords : Sesbania virgata; Hipoxia; Ecological Anatomy.
