A process to enhance germination of a wild pennycress variety

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 ..., , # A process to enhance germination of a wild pennycress variety

## 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...,
