Germination in both the 13 individual PDFUs and the mean are reported, as well as the mean length of seedlings. Forty seeds were placed in each Petri dish per PDFU. A small subset of the seedlings was randomly selected and removed from Petri dishes to make detailed length measurements. N=sample size; SE=standard error.
