| Family Scientific Name: | Poaceae | ||
|---|---|---|---|
| Family Common Name: | Grass Family | ||
| Scientific Name: | Dichanthelium clandestinum (L.) Gould | ||
| Common Name: | Deertongue | ||
| Species Code: | DICCLA | ||
| Ecotype: | Shenandoah National Park, Virginia, Skyline Drive | ||
| General Distribution: | Dichanthelium clandestinum ranges from Nova Scotia and Quebec west to Kansas, Missouri, and Oklahoma, and south to northern Florida and Texas; it prefers moist conditions but somewhat sandy soils and is found in thickets and wooded areas. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | vegetative | ||
| ProductType: | Container (plug) | ||
| Stock Type: | Container plugs | ||
| Time To Grow: | 3 Months | ||
| Target Specifications: | Height: 4-6" Root System: Full, firm plug which leaves no loose soil when pulled. | ||
| Propagule Collection: | Collected in Shenandoah National Park, Virginia, by J. Englert on 8/20-21/92 and the National Plant Materials Center, Maryland, by D. Dusty on 10/1/96, 10/24/97, and 9/28/98. | ||
| Propagule Processing: |
Seed Processing: Seeds are separated from chaff with a 2-screen seed clipper. Seeds/Kg: 830,000. Germination: No test results. Greenhouse germination was 9% of seeds planted, or71 plugs per gram of seed. Purity: 82%. |
||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Propagation Environment: Greenhouse with alternating day/night temperatures (75/68F) and 12-14 hours of daylight extended with high-pressure sodium lights. Container Type and Volume: Seeds are sown in 392 plug trays. Seedlings are transplanted to 72 plug trays. Growing Media: Seeds are sown in Fafard Germinating Mix. Seedlings are transplanted into Sunshine #5 plug mix with 180 day Nutricote (16-8-8) SR fertilizer incorporated @ 0.15lb/cu ft. |
||
| Establishment Phase: |
Sowing Date: February for spring planting; July for fall planting. Sowing/Planting Technique: Seed is surface-sown on germination mix in 392 plug trays, placed on heat mats (set @ 7SF) and misted for 5-7 days. Trays are then moved from mist to bench and seeds are lightly covered with germination mix. Establishment Phase: Seedlings are transplanted to 72 plug flats. Appear to prefer well-drained media. |
||
| Hardening Phase: | Hardening Phase: 2-3 weeks prior to out-planting, fertilization is stopped, water is decreased and greenhouse temperatures are reduced or plugs are moved outdoors. | ||
| Harvesting, Storage and Shipping: |
Total Time to Harvest: About 80 days from germination to finished plug. Harvest Date: Out-planted in spring or fall. Seed storage: Seed bags in seed cooler held at 40 F and 35% relative humidity Seed dormancy: Germination is improved with 5-7 days of bottom heat and mist. |
