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 treatments increase of a wild pennycress line ('MN106NS'). randomised complete block experimental design used with two replications 12 treatments: untreated control; fludioxonil (50 μg ai per g seed); gibberellic acid (GA) soak at 0.05 or 0.01% w/w for hours; pelleting diatomaceous earth commercial binder ± each prior component carnauba wax coating. For all treatments, uniformity stability pelleted were tested, over time (3 14 days 20°C dark) quantified. There consistent increase, weight size (142% 29% on average) seeds pelleting, combination did not vary stability. Total increased compared the control except addition alone. While total germination, use GA as treatment during most effective MN106NS.
