Easy.

Seed collection

Fruit is capsule-like.(1) Seeds can be dispersed by wind.(2)

Pre-sowing treatments

Scarify (weaken) the seed case in sulphuric acid (98%) for 24 min. Follow by letting the seed absorb gibberellic acid (0.1 mmol/L) solution.(3) Seeds that float have lower germination than seeds that sink.(1)
