Conteúdo: | Agricultural crops such as soybean [Glycine max (L.) Merr.] are mesophytes and require an environment which is neither too wet nor too dry for maximum groth and development. Flooding is a common occurrence in many areas of the world (Kozlowski, 1984a) and crops such as soybean are frequently exposed to fooding or waterlogging conditions during the growing season. Temporary flooding may result either from poor soil drainage following irrigation or heavy rain, or from a rising water table because of net water movement into the root zone from adjacent land (Drew, 1988). On a field scale flooding problems occur most commonly on relatively level land, with restricted surface or internal drainage (Stolzy and Sojka, 1984). Soils with these properties are characteristically found in low-lying river deltas or flood plains, on remnant or recessional lacustrian formations, and along low-lying maritime coastal plains. The frequency and duration of flooding have a marked impact on soil properties and on soybean response. Plant or crop responses to flooding vary with plant genotype, soil characteristics, duration, height and timing of the flood, weather, and with the turbulence of the flood water. Compared to the number of studies on plant response to drought, relatively little is known about the physiological response to soybean to excess water. The response of field-grown soybean to waterlogging is partially governed by its response to changes in the soil and climatic environments as a result of the flooding. During and after
