Several environmental factors influence plant photosynthetic process in wetlands, thus, affecting growth, productivity, and overall wetland functioning. Assessment of photosynthetic functioning is critical to the understanding of the range, threshold, and optimal conditions for plant growth in wetlands. In most wetlands, flooding is the predominant environmental factor although in certain wetlands other factors such as periodic drought, salinity, and temperature extremes may also affect plants. This paper focuses on photosynthetic responses to changes in wetland conditions following flooding events. Soil flooding leads to soil anoxia that is accompanied by production of many soil substances, known to be harmful to plants. As a result, wetland plants may suffer periodic stresses leading to physiological dysfunctions and reduced photosynthesis. The contribution of these soil compounds to the overall photosynthetic reductions, as well as plant response mechanisms involved are discussed. Also, additional key references on the topic are provided.
