| Family Scientific Name: | Fabaceae | ||
|---|---|---|---|
| Family Common Name: | Pea | ||
| Scientific Name: | Oxytropis campestris (L.) DC. gracilis (Nels.) Hult. | ||
| Common Name: | Field Oxytrope | ||
| Ecotype: | Central, South-Central Alaska; dry, sandy areas | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Target Specifications: | Root trainer, 10.5 cu.in./cell. Multiple leaves, firm root plug. | ||
| Propagule Collection: | By hand when pods start opening. The seeds are ripe when brown and hard. | ||
| Propagule Processing: | Air dry. Approximately 500 seeds per gram. Tetrazolium test: 85+% viable seed. Clean seed with brush cleaner then hand screen. Store in freezer. | ||
| Pre-Planting Treatments: |
Our best germination occurred when seeds were planted into cells in the fall and subjected to ambient temperature fluctuations. In spring seeds start germinating at approximately 50 degrees F. With a Tetrazolium test of 96%, eleven days after bringing cells into greenhouse, 92% of seeds had germinated. If seed is to be planted in the spring here in Alaska, a slight scarification (fine sandpaper) enables germination to occur. Germination is less. |
||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Soil mix: Upland, well drained. Plant 2 seeds per cell. If planted in the fall, bring into greenhouse by end of March. If planted in the spring, initial propagation site is greenhouse. | ||
| Establishment Phase: | Plants moved to lathhouse to harden off after last frost. Fertilize minimally after true leaves appear. | ||
| Length of Establishment Phase: | Two months | ||
