| Family Scientific Name: | Cyperaceae | ||
|---|---|---|---|
| Family Common Name: | Sedge Family | ||
| Scientific Name: | Carex nebrascensis Dewey | ||
| Common Name: | Nebraska sedge | ||
| Species Code: | CARNEB | ||
| Ecotype: | Idaho | ||
| General Distribution: | Nebraska sedge is found from Alberta and Saskatchewan south throughout the western United States and Great Plains to Nebraska and east to Missouri and Illinois. It inhabits wet meadows and swales in open grasslands from sea level to 2,500 m (0 to 8,202 ft). | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Propagule Collection: | Mature female spikes containing the achenes can be collected by hand stripping the flowering stems in late summer and early fall. Filled, ripe seeds will shatter or easily shake out of the seed head. | ||
| Propagule Processing: |
Store collected material in a dry place until cleaning. Large collections could be cleaned with a hammermill or with a clipper "Office" fanning mill, using a Number 8 top screen and a Number 20 screen, with the airflow adjusted to a very slow speed. Additional cleaning to remove the perigynia improves germination. Perigynia can be removed by various methods, but a brief, light rubbing of achenes with sandpaper is an easy method for small quantities. |
||
| Pre-Planting Treatments: |
Removal of the perigynium, the saclike structure around mature achenes, either with forceps or sandpaper, provided sufficient scarification to significantly increase total germination about 50% compared with that of nonscarified achenes. A combination of scarification and 32 d of cold, moist stratification resulted in 25% higher total germination than stratification alone. Cold, moist stratification also improved germination rate. Stratification of scarified achenes with Sphagnum peat moss resulted in 17% more germination than when scarified achenes were stratified in distilled water only. Our results indicate Nebraska sedge can be efficiently germinated in nurseries if perigynia are removed by scarification and achenes stratified 32 days at 3øC (37øF) with a Sphagnum peat moss substrate. More methods can be found in Hoag et al. 2001. |
