| Family Scientific Name: | Cyperaceae | ||
|---|---|---|---|
| Family Common Name: | Sedge family | ||
| Scientific Name: | Scirpus microcarpus J. Presl & C. Presl | ||
| Common Name: | Panicled bulrush | ||
| Species Code: | SCMI2 | ||
| Ecotype: | Yosemite National Park | ||
| General Distribution: | North America with the exception of the southeast. | ||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 10 cubic inch conetainer | ||
| Time To Grow: | 5 months | ||
| Target Specifications: | Healthy root development filling the 10 ci conetainer. | ||
| Propagule Processing: | Seed can be separated from plant material by hand or using a hammermill or brush machine. Seed can be cleaned using an air-screen cleaner with 1.40 mm top screen and blank bottom screen and light air. Unmilled seed retains the perianth bristles that can cause seed to clump together, though we did not find that this affected planting or establishment. | ||
| Pre-Planting Treatments: | Seed is stored in cool-dry conditions with temperatures of approximately 10° C (50° F) and relative humidity of 20 to 30%. Flats were placed outside after planting to allow for natural over-winter stratification beginning in mid-November. Flats were brought into the greenhouse when outdoor conditions began to dry the soil in March. | ||
| Establishment Phase: | We used Sunshine Mix #4. No fertilizer is added to the soil mix. Five to ten seeds are placed on the soil surface and pressed for good seed-to-soil contact. Seed is lightly covered with pea gravel. The soil surface is kept moist with 20 minutes of daily irrigation from overhead sprinklers for the first 30 days. Day time greenhouse temperatures range from 24 to 29° C (75 t 85° F). Night time temperatures average around 21° C (70° F). | ||
| Length of Establishment Phase: | 8 weeks | ||
| Active Growth Phase: | Our seed lot had very high viability and most cones had multiple plants in them that required thinning. After full establishment, plants are fertilized once per week with Miracle Grow All Purpose Plant Food (15-30-15). After 30 days the irrigation schedule is changed to 40 to 60 minutes every other day to encourage root growth. | ||
| Length of Active Growth Phase: | 4 months | ||
| Hardening Phase: | We backed off the water to 60 minutes every 4 or 5 days. | ||
| Length of Hardening Phase: | 1 week | ||
| Harvesting, Storage and Shipping: | Plants were deeply watered just prior to shipping. Plants were shipped in a 10° C (50° F) refrigerated truck for 2 days. | ||
