Trial 4: Freshwater vs. dry storage for Plantago maritima, Hudsonia ericoides, and Limonium carolinianum, and the use of saltwater vs. freshwater irrigation for Plantago maritima.

↵Notes: This table shows average germination rate and the average number of days until germination ± SE (standard error). The trial used 3 replicates with 50 seeds per replicate. An * indicates that the treatment performed significantly better (P < 0.05) than all other treatments. For Hudsonia ericoides, 2 of the 3 replicates in the wet treatment did not germinate. For P. maritima, the dry storage/freshwater treatment was significantly different from the wet storage/freshwater treatment.
