| Family Scientific Name: | Oleaceae | ||
|---|---|---|---|
| Family Common Name: | Olive family | ||
| Scientific Name: | Fraxinus anomala Torr. ex. S. Watson | ||
| Common Name: | Singleleaf Ash | ||
| General Distribution: | Singleleaf ash is native to the southwestern United States from Wyoming, South to New Mexico and west to California. In Utah it is common on the Colorado Plateau and as far north as the Uintah basin and west to Washington County. | ||
| Known Invasiveness: | Singleleaf ash is not invasive. | ||
| Propagation Goal: | Cuttings | ||
| Propagation Method: | Vegetative | ||
| ProductType: | Propagules (seeds, cutings, poles, etc.) | ||
| Time To Grow: | 7 | ||
| Target Specifications: | Rooted cuttings | ||
| Propagule Collection: | Cuttings were collected on 11 June 2014 early in the morning from field-grown plants. | ||
| Propagule Processing: | Cuttings were immediately prepared for treatment. | ||
| Pre-Planting Treatments: | Cuttings were sorted for uniformity (average of 77 mm in length), lower leaves stripped, stems wounded with a 1 cm side scrape, and dipped 15 mm deep in 2000 ppm IBA and 1000 ppm NAA as Dip-n-Grow in 25% ethanol for 5 seconds with no shake. Cuttings were stuck in 4:1 perlite:peat rooting substrate in containers (6.5 X 6.5 X 8.9 cm). | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Cuttings were randomly assigned to either a glass greenhouse or a Nearing frame. Bottom heat was supplied in both environments at 22°C. The greenhouse was misted with a Phytotronics VPD controller set at 30 VPD with 12 second misting time. The Nearing frame was misted every 10 minutes for 15 seconds. Mist systems ran from 6:00 AM to 9:00 PM. Greenhouse temperatures were at 65/60ºF DT/NT while Nearing frames were at ambient temperatures with no covering (except for the bottom heat). | ||
| Establishment Phase: | After roughly 5 weeks, cuttings in both the greenhouse and Nearing frame were 25% rooted and the Nearing frame plants were healthier in appearance. At 7 weeks, 50% of the cuttings in the Nearing frames were rooted while only 41% of those in the greenhouse were rooted (data not statistically analyzed). After 5 weeks cuttings averaged a little more than 2 roots per cutting. | ||
| Length of Establishment Phase: | 7 weeks | ||
| Other Comments: | We at the Center for Water Efficient Landscaping believe that singleleaf ash has potential as a water conserving landscape tree. However, its propagation and distribution should be limited until its resistance or susceptibility to the introduced emerald ash borer (Agrilus planipennis) is known. | ||
