Family Scientific Name: Anacardiaceae
Family Common Name: Cashew family
Scientific Name: Rhus trilobata Nutt.
Common Name: Skunkbush sumac
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.
