68 WORKSHOP 9 (Abstr. 662–666) Ornamental Plant Breeding in the Midwest

There is increased interest among ornamental plant growers to identify native shrubs that can be produced commercially for the nursery and landscape industry. Native shrubs must propagate readily from stem cuttings because this method yields uniform

Interest in native plant species for general landscape planting, mitigation of environmental impact and ecological restoration plantings continues to expand with public awareness of environmental quality. An expanding area of opportunity exists for the landscape horticulture industry to supply non-traditional plant materials to support landscape planting with native species. To capitalize on the opportunity, horticulture and landscape architecture students and practitioners must become knowledgeable of species native to their region. Video is a useful medium for increasing such knowledge. This presentation will review the development, production, distribution and content of six video programs that survey the native herbaceous flora of Indiana prairies and woodlands. Each program is less than 30 minutes in length, to facilitate classroom use and presentation in broadcast formats. Botanically correct nomenclature is presented graphically as each species is introduced. The narration includes botanical, ecological and horticultural information, but emphasizes plant lore to increase interest for general audiences and provide memory clues for those attempting to learn the plants. This project, supported by the Indiana Association of Nurserymen, provides a good example of how horticultural industries can become leaders as the public expands its demand for improved environmental quality.

Five Utah Native Plant Propagation workshops during Mar. 2005 supplied 100 participants with specialized containers and potting mix, native plant seed, resource booklet, lecture, and instructor supervision during the hands-on workshop portion. Forty-three participants responded to a Sept. 2005 follow-up survey. Seedling survival averaged 6.4 seedlings per tray of 72 cells, or 8.8%. Only 36% of the participants used the resource booklet after the workshop. Most survey respondents did not cite particular reasons for seedling failure. Seed propagation workshops are challenging due to: 1) wide variance in participants' horticultural experience; 2) limited materials and resources; and 3) inherent inconsistencies in native plant seed viability. Before attending future seed propagation workshops, registrants will receive seedling cultivation information to improve success rates.

Wildflowers/native plants are increasingly being used in landscapes, especially in low maintenance areas. Buffalograss is also receiving attention as a low maintenance grass. Establishing wildflowers in buffalograss would be useful in sites where mowing occurred only once in the fall, such as with minimeadows. Four experiments were conducted to study the establishment of wildflowers in buffalograss. Survival of wildflowers after one year was 88% when wildflowers were planted as greenhouse grown transplants and buffalograss plugged in 2 weeks later, 67% when one-year-old field grown wildflowers were transplanted into buffalograss plugged at the same time and 48% when greenhouse grown wildflowers were transplanted into established buffalograss. Establishment of wildflowers overseeded into established buffalograss sod was very low. There were significant differences in wildflower survival within each study. Species which performed well in buffalograss included Leadplant, Blue Fax, Purple Prairie Clover, Little Bluestem and Stiff Goldenrod.

Texas is botanically diverse with approximately 5500 native plants identified: east Texas contains about 40% of the total. While most species are stable, many are classified as rare, threatened, vulnerable, or endangered. Databases for east Texas plant communities and vegetative analyses are numerous. However, they are not yet integrated into easy-to-sort-and-query computer files. Computer-Assisted Drafting (CAD) and Geographic Information Systems (GIS) technology offers powerful applications to the storage, management, and spatial analysis of species inventories, plant community dynamics, and long-term habitat monitoring. At SFASU, the College of Forestry's GIS Center is being utilized to develop comprehensive east Texas resource inventories on a ten-station HP Apollo/ArcInfo platform. In the horticulture program, a twenty-station PC/AutoCad teaching laboratory is being used to create layered maps of the SFASU Arboretum, the on-campus landscape and off-campus plant communities. The integration of CAD and GIS projects through a DXF format takes advantage of the attributes of both technologies.

In Texas, 5,500 native species are distributed over an area comprised of ten regional habitat types. In the Piney Woods region of east Texas, 2,300 plant species occupy 15 million acres. In east Texas, the USFWS has identified 4 species that are federally endangered and 15 that are candidates for that listing. Interest in protecting rare plant habitats and reintroducing those species into similar and appropriate ecosystem types has led to new tools in research and development. Remote sensing is one; this technology is used to derive information about the earth's land and water areas from images acquired at a distance Multispectral and spatial techniques are applied to process and interpret remote sensing imagery for the purpose of producing conventional maps, thematic maps, reource surveys, etc., in the fields of agriculture, botany, archeology, forestry, geography, geology. and others. Remote sensing is used to classify vegetation, interpret forest photogrammetry, estimate timber production, and identify crops, individual plants and leaf structure. This specific project was initiated to determine the potential of remote sensing as a tool to locate known and new rare plant communities in east Texas. To develop benchmark data, a Daedalus scanner image of a previously surveyed and AutoCAD® mapped area, the Vista forest on the SFASU campus, was utilized to develop correlations between imagery, vegetation types and species. By inserting various scan images under the Vista forest AutoCAD® map, known tree species were analyzed through their specific spectral emission characteristics across nine bands. This pilot project has indicated that it is simple to separate pines from hardwoods and illustrate major land use features. However, separation at the species level or groups of species has not been achieved. This paper will trace the history of this project, describe problems and obstacles encountered, and make recommendations for future strategies.

67 POSTER SESSION 9 (Abstr. 566-589) Propagation/Cell & Tissue Culture: Turf/woody Plants

Ten plant species native to southeast Alaska and surrounding regions were selected based on their value as ornamentals, food crops, disturbed site revegetation, and traditional Native American uses. Between 2003–05, seeds, cuttings, rhizomes, and bulbs from the 10 native plant species were collected in Sitka, Alaska, and propagated according to existing plant propagation protocol for each species. The most successful propagation method for each species was determined from field trials. This information was provided through workshops and Extension publications to gardeners in southeast Alaska and other parts of Alaska. The purpose of this project was to enhance growing local native plants as ornamentals, food crops, in disturbed site revegetation and for traditional Native American uses, particularly among native elders unable to collect these plants in the wild. A secondary purpose was to create a market for native plants in southeast Alaska and spawn a cadre of local cottage market gardeners to grow native plants for existing small nurseries. The 10 species selected included: Cornus canadensis, C. stolonifera, Empetrum nigrum, Fritillaria camschatcensis, Linnaea borealis, Oplopanax horridus, Rubus chamaemorus, Vaccinium parvifolium, Vaccinium ovalifolium, and Viburnum edule.
