Background information and definitions
Exposing seeds to cold temperatures before planting can help to break seed dormancy and encourage germination. Some species with physiological dormancy must experience a cold period before germinating, in order to break down chemicals that inhibit germination or stop the production of these chemicals. 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,
