Effect of Soil Reduction Intensity

Soil anaerobiosis results in plant stress symptoms similar to those caused by drought stress. Among these are stomatal closure and reduction in net carbon assimilation. Photosynthesis in plants susceptible to flooding rapidly declines under anaerobiosis. Reduction in photosynthesis in response to flooding has also been reported for flood-tolerant species.
