Family Common Name: | Borage family | ||
Scientific Name: | Hackelia venusta (Piper) St. John | ||
Common Name: | Showy stickseed | ||
Species Code: | HAVE | ||
Ecotype: | Dry, eastern slopes of Cascade Mtn range with ponderosa pine. | ||
General Distribution: | This species of Hackelia is only found in Chelan County in the Washington Cascade Mountain Range. | ||
Propagation Goal: | plants | ||
Propagation Method: | vegetative | ||
ProductType: | Container (plug) | ||
Stock Type: | 165 ml capacity Hillson Rootrainers | ||
Time To Grow: | 16 Weeks | ||
Target Specifications: | 15-cm-long, firm root plug | ||
Propagule Collection: | Propagules were rooted microshoots. | ||
Pre-Planting Treatments: | Rooted propagules were removed from sterile, glass tubes. The roots were gently washed under running water to remove any remaining agar. | ||
Establishment Phase: | Rooted propagules were planted in rootrainers containing a 1:1 volume of Sunshine peat and perlite. Relative humidity was 90% and progressively decreased to ambient over the course of 4 weeks. Plantlets were kept in 70% shade and slowly acclimated to normal greenhouse sunlight over 4 weeks. | ||
Length of Establishment Phase: | 1 month | ||
Active Growth Phase: | Acclimated plantlets were then fertilized with 20:20:20 (N:P2O5:K2O) at 200 ppm N twice a week for 8 weeks. | ||
Length of Active Growth Phase: | 2 months | ||
