Sesbania virgata (Cav.) Pers. is a bush, pioneer and occurs naturally in Brazil. It belongs to the Fabaceae family it indicated for recovery of degraded areas because its rusticity capacity tolerate flooding. The present research was carried out investigate ability S. plants adapt flooding conditions. Plants containing six expanded leaves were placed masonry tanks subjected following conditions: control (well watered), soil-waterlogging (water setup level 1 cm above soil surface – roots parts stems flooded) complete submergence (whole plant flooded). evaluations conducted on day stress induction after 7, 14, 21, 28, 35, 42, 49 56 days treatment. After 15 return normoxic environment, survival assessed. Growth (height, dry mass shoots roots), vigour, carbohydrate content activity enzymes involved anaerobic metabolism (lactate dehydrogenase, pyruvate decarboxylase alcohol dehydrogenase) also evaluated. Our results suggested that sesbania are tolerant flooding, they can survive being submerged days. reasons this tolerance include accumulation use carbohydrates roots, maintenance growth activation metabolism, particularly steps catalysed by dehydrogenase.
