Tips
Keep seeds cold-stored for several months before sowing; in vitro conditions significantly enhance germination rates (100% under specific protocols); sow in lightly shaded position; maintain consistently moist substrate; seeds deteriorate quickly in storage at room temperature; winged seeds perform better than dewinged seeds
