Description:
Terminal stem cuttings from 5-year-old Fraser fir (Abiesfraseri (Pursh) Poir.) stock plants were collected in early fall, when in a state of rest or winter dormancy. Cuttings were subjected to dark storage at 4 °C for 0, 2, 4, 6, 8, 10, or 12 weeks. Following storage, and prior to insertion into a rooting medium, cuttings were subjected to one of two treatments: nontreated, and wounding + indolebutyric acid (IBA). Cuttings received short- or long-days during a 10-week rooting period. Nonchilled cuttings did not root or break bud. High percent rooting occurred after 4–6 weeks of chilling, whereas visible terminal bud activity peaked after a 10-week chill. Rooting was primarily contingent upon IBA treatment and chilling, although long days had a strong promotive effect when cuttings were chilled less than 6 weeks.
