| Description: |
The area was calculated automatically in ImageJ by applying a colour threshold to distinguish explants from the background and subtracting the latter to obtain a 2D projection as a proxy for the regenerative potential.
Protocol b: 7-mm-long apical root segments were excised from 10-day-old seedlings, grown under warm white fluorescent tungsten tubes (70 µM m^-2 s^-1; 14/10 h light/dark regime) at 21 °C. Next, explants were preincubated on callus induction medium (CIM; B5 supplemented with 2.2 µM 2,4-dichlorophenoxy acetic acid and 0.2 µM kinetin) for 4 days, before being transferred to SIM. |
