Resumo: | This paper presents a study on the respiratory metabolism of germinating seeds of Inga sessilis subjected to normoxia, hypoxia and anoxia. Although it is typical of environments where waterlogging seldom occurs, 40% of its seeds are able to germinate under hypoxia; yet, anoxia periods over 96 h are lethal to the seeds. Ethanol is the main product of the seeds anaerobic metabolism, but the steep increase in lactate after 24 h anoxia or 48 h hypoxia may explain the drop in seed viability.
