Background information and definitions
Acids and bleach may weaken the seed coat, increasing its permeability to water and gases which are essential breaking dormancy and inducing germination (Baskin & Baskin 2014). They may also sterilize seeds, killing fungi that may otherwise reduce germination rates. Hormones are widely used in agriculture and horticulture to stimulate germination and growth (Small & Degenhardt 2018). Other molecules such as nitrates act as signals within plants and may stimulate germination (Alboresi et al. 2005).
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.
