Notes: Seeding and 7-day thermopriming (light red) in climate chambers, one single BTH application (yellow), and one single salt stress application (blue) during a 20-week greenhouse cultivation (light grey), as well as four dates for leaf sampling (dark red vertical lines) and 7-week-long duration of fruit sampling (dark grey) specific to each of the six treatments over the whole experimental duration in weeks after sowing. Treatments: B represents the BTH treatment, P represents thermopriming, C represents control conditions (non-primed or non-stressed groups), and S represents salt stress (e.g., C–C: control conditions (non-primed) instead of priming or BTH treatment and non-stressed (C) at the time of the salt stress).
