Date	Result	T0	T50	Pre-treatment \| Germination medium \| Incubator: Photoperiod / Thermoperiod
May-17	80%	14	14	500 mg/L gibberellic acid for 24 h; 1% agar; Incubated under winter conditions
May-17	72%	7	14	500 mg/L gibberellic acid for 24 h; 1% agar; Incubated under spring/autumn conditions

Result: Maximum percentage of germination observed.
T0: Number of days before first germinant observed.
T50: Number of days to achieve 50% germination.
Pre-treatment: The initial treatment that the seeds received prior to placement on germination media.
Germination medium: The substrate that seeds were placed on for the duration of the germination experiment.
Incubator conditions:
Photoperiod: The duration of light exposure that the seeds were subject to during a 24 hour period.
Thermoperiod: The constant or diurnal temperatures that seeds were subject to during a 24 hour period.
Winter conditions: 15°C 20 h (3am→11pm); 5°C 4 h (11pm→3am) / 10 h light (8am→6pm); 14 h dark (6pm→8am)
