| Family Scientific Name: | Poaceae | ||
|---|---|---|---|
| Family Common Name: | Grass | ||
| Scientific Name: | Calamagrostis canadensis (Michx.) P. Beauv. | ||
| Common Name: | Bluejoint | ||
| Species Code: | CACA4 | ||
| Ecotype: | Rocky Mountains, western Wyoming | ||
| General Distribution: | Throughout North America with the exception of the southeastern states. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 10 cubic inch container | ||
| Time To Grow: | 3 Months | ||
| Target Specifications: | Healthy root development filling the 10 cubic inch container. | ||
| Propagule Collection: | Seed is most commonly collected by hand. Fruiting heads can be cut from stems using shears or a hand scythe. Seed is hard and brown when ripe. | ||
| Propagule Processing: | Seed is air dried in paper sacks for several weeks prior to processing. Seed is removed from stem using a hammer mill with a 0.6 cm (0.25 in) screen. Seed is cleaned using an airscreen cleaner with a 1.55 mm screen and light air. Purities of over 95% are typical. There are approximately 3.8 million seeds/lb. Viability depends on seed fill. A kerosene heater "pop test" is used for quick estimates of seed fill (Tilley et al 2010). Lots with poor viability are re-cleaned with increased air. | ||
| Pre-Planting Treatments: | Seed is stored in cool-dry conditions with temperatures of approximately 10ø C (50ø F) and relative humidity of 20 to 30%. Seed is not stratified prior to planting. | ||
| Establishment Phase: | Soil is a 1:1:1 mix of coconut fiber, compost and perlite. No fertilizer is added to the soil mix. Five to 25 seeds are placed on the soil surface and pressed for good seed-to-soil contact. Seed is not covered with any soil or sand, but kept moist with an overhead mist irrigation schedule of 2 minutes/hr from 9:00 am to 5:00 pm for the first 30 days. Day time greenhouse temperatures range from 32 to 43ø C (90 to 110ø F). Night time temperatures average around 30ø C (85ø F). Grow lights are kept on during nighttime hours. | ||
| Length of Establishment Phase: | First emergence occurs around 3 to 5 days after planting under temperatures and moisture conditions specified. Full stands (90-100%) are reached in 12 days. | ||
| Active Growth Phase: | After full establishment, plants are fertilized once per week with Miracle Grow All Purpose Plant Food (15-30-15). After 30 days the irrigation amount is increased to 3 minutes/hr from 9:00 am to 5:00 pm and grow lights are turned off. Greenhouse day time temperatures are reduced to 30 to 32øC (85 to 90ø F). | ||
| Length of Active Growth Phase: | Three months. | ||
| Hardening Phase: | Heat is turned off and temperatures reduced to ambient conditions. Watering is discontinued approximately 3 days prior to delivery. | ||
