| Family Scientific Name: | Chenopodiaceae | ||
|---|---|---|---|
| Family Common Name: | Goosefoot Family | ||
| Scientific Name: | Krascheninnikovia lanata (Pursh) A. Meeuse & Smit | ||
| Common Name: | Winterfat | ||
| Ecotype: | Madrean Archipelago | ||
| General Distribution: | Found on slopes and plains, sometimes on alkaline soils from 2,000–7,000 ft (500-2100m) (Ogle et al., Flora of North America Editorial Committee 1993+). Does not tolerate excessive moisture or acidic soils (Ogle et al.). Important forage for both livestock and wildlife (Ogle et al.). | ||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Propagule Collection: |
Collect by hand when seeds are easily separated from plant. Bracts surrounding seeds should be brownish and slightly crumbly. If they are green and flexible, the seeds are not ready. |
||
| Propagule Processing: |
Seeds are fairly delicate and can easily be damaged. For this reason, it is advisable to maintain viability by leaving the four-winged, white fluffy bracts on the seed for storage and planting (Ogle et al.). Seed can generally be stored for 1-2 years under optimal conditions (dry, 5°C). However, viability may decrease by as much as 50% in the first year of storage and it decreases drastically after 2-3 years of storage (Ogle et al., Majerus 2003). For this reason, seed should be planted as soon after collection as possible. |
||
| Establishment Phase: |
Germination rates rely heavily on the age of the seed. Fresh (1-2 years old) seed germination rates are typically 85-95% but seed 3 years old or older has germination rates of 0-15%, even under optimal storage conditions (Ogle et al., Majerus 2003). Seed should be sowed on soil surface or up to ¼ inch deep, but no deeper (Ogle et al.). It is unknown if removing the bracts has any effect on germination rates, so this may be something to test (Majerus 2003). |
