Overcoming physical seed dormancy in priority native species for use in arid-zone restoration programs

The relative effectiveness of wet- and dry-heat treatments on alleviating physical dormancy (PY) of seeds of seven species of Fabaceae and five species of Malvaceae was determined to optimise seed handling procedures for ecological restoration. Seeds of all species were treated at different temperatures (40−100°C) for various durations (2 and 5 min of wet heat, and 5, 10 and 30 min of dry heat). Prior to treatment, seeds of all species exhibited...
