Family Scientific Name: Cyperaceae
Family Common Name: Sedge family
Scientific Name: Carex multicostata Mackenzie
Common Name: manyrib sedge
Species Code: CAMU6
Ecotype: Seeds were collected from Crater Lake.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Time To Grow: 0
Pre-Planting Treatments: Seeds were sown into cone-tainers filled with Sunshine # 1 (a soil-less, peat-based media) amended with micro-nutrients (Micromax) and a slow-release fertilizer (Osmocote 14-14-14). Flats were covered with polyethlene bags and placed in the walk-in cooler for 90-days. After stratification flats were placed in greenhouse set at moderate temperatures (70 degree days/50 degree nights.)
Trays removed at 5 weeks resulted in good emergence after two weeks. Seedlings were vigorous and germination was estimated at 80%. No significant differences in emergence or seedling vigor were noted between 5, 10 or 16 week-stratified seeds. 0 germinants were observed in control flats.
