Abstract:Planting vigorous cuttings that quickly develop shoots and roots is essential to the biological and economic success of willow biomass crops. Current recommendations are that cuttings should be planted within 2–4 days of being removed from long-term cold storage at −4 °C. However, maintaining this short time period is not always feasible. Results from greenhouse and field experiments indicated that leaving cuttings out of −4 °C long-term cold storage for up to 12 days before planting did not have a significant impact on survival or biomass production. For cuttings removed from long-term cold storage 23 days before planting, survival and per tree biomass production were lower for three of the four clones tested in a field trial. Returning cuttings to a −20 °C freezer 5–9 days after removal from −4 °C long-term cold storage, reduced the proportion of cuttings that developed roots or shoots, and shoot biomass of all clones. However, returning cuttings to either a +2 °C cooler or a −4 °C freezer had no effect on shoot biomass after 3 weeks of growth. Returning cuttings to supplemental cold storage at +2 to −4 °C may extend the time that cutting viability can be maintained after being removed from long-term cold storage and thawed. Returning cuttings to a −20 °C freezer for supplemental storage is not recommended.
