... To investigate the potential role of ethylene as a germination stimulus, additional replicates of 20 seeds were prepared as previously described but imbibed in distilled water for 24 h and exposed to an 80 mg.L − 1 Ethephon (Sigma Aldrich, Germany) for a further 24 h prior to being placed in 20 mL sealed plastic tubes containing 15 mL of either acidic, neutral or alkaline germination media solution. Ethephon is known to gradually release ethylene gas in solution, and ethylene is a known a germination stimulant for many aquatic and wetland plant species (e.g., Baskin and Baskin, 2014;Cross et al., 2014Cross et al., , 2015Cross et al., , 2018bPrausová et al., 2014). Seeds were then incubated at 21 or 25 • C on a 15-h photoperiod or in constant darkness for six weeks as previously described. ...
