| Family Scientific Name: | Betulaceae | ||
|---|---|---|---|
| Family Common Name: | Birch family | ||
| Scientific Name: | Betula nana L. exilis (Sukaczev) Hult‚n | ||
| Common Name: | Arctic Dwarf Birch | ||
| Ecotype: | Open low mesic shrub birch-ericaceous shrub community near Purinton Creek, Talkeetna Mtns., Alaska | ||
| General Distribution: | Most of Alaska eastward through YT, NT, and Nunavut to Hudson Bay and dipping into extreme northern BC, AB, SK, and MB. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Target Specifications: | Firm root plug, multiple leaves. | ||
| Propagule Collection: | Collection made in late summer/early Fall. | ||
| Pre-Planting Treatments: | No pretreatment necessary if sown in the Fall. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Seed is sown in the Fall in Spencer-Lemaire rootrainers in facultative soil mix. Seeds have been lightly covered. The trays are stored in a sheltered area where they are exposed to ambient winter temperatures. | ||
| Establishment Phase: |
In Spring, trays are moved to the greenhouse. Germination exceeded 60% within 5 weeks. |
||
| Hardening Phase: | Trays are removed from the greenhouse to an outside sheltered area for hardening after young plants have multiple true leaves. | ||
| Other Comments: | Because of taxonomic confusion within the genus Betula and widespread hybridization, especially with B. nana ssp. exilis and B. glandulosa, this protocol could also apply to B. glandulosa as described in Flora of North America. | ||
