title: Data from: A process to enhance germination of a wild pennycress variety

description: Pennycress is an emerging oilseed crop, but some improved lines still
 exhibit seed dormancy that may impede germination and establishment. A
 laboratory study was conducted in 2021 to identify seed treatments to
 increase germination of a wild pennycress improved line
 ('MN106NS'). A randomised complete block experimental design was
 used with two replications and 12 seed treatments: untreated control;
 fludioxonil (50 μg ai per g of seed); gibberellic acid (GA) soak at 0.05
 or 0.01% w/w for 12 hours; pelleting with diatomaceous earth and a
 commercial binder ± each prior component and a carnauba wax coating. For
 all treatments, uniformity and stability of pelleted treatments were
 tested, and germination over time (3 to 14 days at 20°C in dark) was
 quantified. There were consistent increases in weight and size (142% in
 weight and 29% in size on average) of seeds with pelleting, and pelleting
 combination treatments did not vary in stability. Total germination
 increased compared to the control with all seed treatments, except the
 addition of fludioxonil alone. While all pelleting treatments improved
 total germination, the use of GA as a soak treatment or as an addition
 during seed pelleting was most effective to increase germination in
 MN106NS.

 DOI: [10.5061/dryad.2v6wwq01b](10.5061/dryad.2v6wwq01b) ## Description of
 the data and file structure This dataset contains germination data and
 seed size information about one pennycress line after being treated with
 one of 12 seed treatments. Procedures were described within the published
 article for building seed pellets on pennycress containing different
 components resulting in 8 tested combinations. One additional treatment
 consisted solely of treatment with fludioxonil fungicide, and two positive
 treatments were generated with soaking seeds in a gibberellic acid A4+A7
 solution at 0.01% w/w or 0.05% w/w concentration. The final treatment was
 an untreated control. Data collected over time included cumulative
 germination over 14 days, and information related to seed weight, seed
 diameter (with and without pelleting), and pellet stability. Missing data
 for a given variable within a plot is denoted solely with a “.” value as
 data was not or could not be collected in the specific instance. ### Files
