| Family Scientific Name: | Poaceae | ||
|---|---|---|---|
| Family Common Name: | Grass | ||
| Scientific Name: | Phleum alpinum L. | ||
| Common Name: | Alpine timothy | ||
| Species Code: | PHAL2 | ||
| Ecotype: | Collected at Mount Rainier National Park; near Tipsoo lake in wet meadows, 5,000 to 6,000 ft elevation | ||
| General Distribution: | Western US; South Dakota; Michigan, also Northeast in Maine and New Hampshire. Occurs in wet meadows, bogs, and other wet places. | ||
| Propagation Goal: | seeds | ||
| Propagation Method: | seed | ||
| ProductType: | Propagules (seeds, cuttings, poles, etc.) | ||
| Stock Type: | seed | ||
| Time To Grow: | 2 Years | ||
| Target Specifications: | Clean seed free of noxious weeds; approx 1,100,000 seed / lb. Native -collected lots tested at 98% germination after a 7-day prechill. | ||
| Propagule Collection: | Hand stripped into paper sacks at maturity; ripened seed is retained for a short time on plants before shattering. Seed ripens in September in collection zone. | ||
| Propagule Processing: | Small lots hand rubbed or threshed with a geared-down hammermill; air-screened with office clipper, 1/14" round screen, low air flow. | ||
| Pre-Planting Treatments: | 7-day prechill for seed testing; or direct-sown into field in early April at Corvallis | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Fine, weed-free seed bed prepared; seed shallowly drilled with a Planet Jr. - #10; 2.4 lbs /ac bulk seed rate resulted in fair stand establishment. | ||
| Establishment Phase: | Supplemental sprinkler irrigation supplied as needed during stand establishment - through July of the first year. Small seedlings grow slowly at first and are susceptible to weed competition. Broadleaf weeds controlled with 2,4-D and Banvel at label rates; grassy weeds controlled by "spot-wicking" applications of Roundup herbicide. Ammonium nitrate (50 lbs N / ac) and 15 lbs/ ac Sulfur was applied in March and again in May to established field, additional 50 lbs N /ac ammonium nitrate applied again in December. | ||
| Length of Establishment Phase: | 1 year; little to no seed production during first year | ||
| Active Growth Phase: | Early spring growth (March and April) often affected by rust / fungi; these foliar diseases were controlled with 2 to 3 applications of Tilt and Bravo applied at label rates, prior to boot stage. | ||
| Length of Active Growth Phase: | April to July at Corvallis PMC | ||
| Hardening Phase: | na | ||
| Length of Hardening Phase: | na | ||
| Harvesting, Storage and Shipping: | Seeds hand stipped at PMC in late June / early July - methods same as for native colleciton. Seeds held in cool, dry storage in cloth sacks. | ||
| Length of Storage: | unknown | ||
| Other Comments: | Individual plants survived fairly well from year to year at Corvallis although the overall stand density and vigor was weak; seeding at higher rates might be helpful but even established plants did not compete well with grassy weed species, for which there are no chemical controls available. | ||
