| Species Code: | RHUTRI | ||
| General Distribution: | R. trilobata is found throughout the western United States and Canada. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Propagule Processing: | Seeds exhibit physical-physiological dormancy. | ||
| Pre-Planting Treatments: |
Seeds are scarified and cold stratified for 40 days and germinate in spring. Seed germination is stimulated by the presence of charred wood or aqueous extracts of it: 27% increase in germination as compared to control. Seeds germinate at 23 C. Germination was greater in light than dark. In another study,seeds are treated with dry heat at 120 C for 5 minutes for increased germination. |
