Background information and definitions
Heating seeds before planting can help to break seed dormancy and encourage germination. Seeds of some species (with physiological dormancy) must experience high temperatures before germinating, in order to break down chemicals that inhibit germination or stop the production of these chemicals. For other species (with physical dormancy), heat can increase the permeability of the seed coat to water and gases, which are essential for germination. For a database of seed dormancy class by species, see Baskin & Baskin (2014).
To be summarized as evidence for this action, studies must have explicitly compared the performance of treated and untreated seeds. Studies that simply report the performance of treated seeds are not summarized here. Studies do not have to be in flooded/saturated soils, as long as they involve wetland-characteristic species.
