Increasing and upgrading nursery production of yellow poplar

Germination, survival, and growth of yellow-poplar were responsive to various seed treatments. Chilling the samaras in sealed polyethylene bags at a constant 2° C for 5 months was superior to nursery pit stratification for periods from 5 months to 2 0 years. High sowing rate reduced germination and survival, probably the result of increased root competition. Application of gibberellic acid (GA) to the seed increased percentage germination and height growth, and reduced stratification requirements.
