| Species Code: | PYRA | ||
| Ecotype: | seeds were collected from Lane Co., Oregon near Eugene | ||
| Propagation Goal: | seeds | ||
| Propagation Method: | seed | ||
| ProductType: | Propagules (seeds, cuttings, poles, etc.) | ||
| Time To Grow: | 0 | ||
| Target Specifications: | containerized plants to be used from small-scale seed increase. | ||
| Propagule Collection: | Pappas and seeds are collected when it "puffs" out. | ||
| Propagule Processing: | Seeds brushed in a lab-sized Westrup brush machine (using a sandpaper drum), this removed pappas and some hairs from the seed, it was then cleaned using a small air screen machine. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
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 of cone-tainers were placed in cooler for 120 days cold-moist stratification. Some seeds germinated whlie in the cooler, however, most of the germination occured after the seeds were moved to a greenhouse set at moderate temperatures (70degree days and 50 degree nights). | ||
| Other Comments: | Plants grew slowly the first year and none of them flowered. Some flowered the second year. Full flowering occured on the third growing season. | ||
