Fungicide Data, Amber Johnson
Fungicide Data, Amber Johnson
ScholarsArchive Data
This dataset contains emergence, biomass, and fungal biomass data collected during a laboratory study examining the effects of soil fungal level and seed coating treatment on the growth of bluebunch wheatgrass (Pseudoroegneria spicata). Pathogenesis from soil and seed-borne fungus can limit success when restoring native species. Fungicides can combat fungal pathogens, but in some studies, fungicides treatments are ineffective at improving seedling emergence over untreated, control seed. These studies suggest low fungal presence due to dry conditions may be the cause of the ineffectiveness of fungicide treatments for some years and sites. This study tested if fungicide treatment …

This file contains the data description for the Larson2023_Slow-release of GA3 Hormone… Supplementary File.
The excel file contains four worksheets: 1) Palmer’s germination, 2) Palmer’s biomass, 3) germination other species, 4) biomass other species. Blank cells indicate either no coating was used or there was no plant.
1) “Palmer’s germination” and “germination other species” A) Temp (o C): germination chamber temperature setting B) Species: common name of penstemon species tested (“germination other species” only) C) Treatment: seed coating treatment D) Final Germination percentage: percent of seed that germinated. E) FGP: final germination percent in decimal form F) Time to 50% …

Gibberellic Acid Data, Amber Johnson
ScholarsArchive Data
This dataset contains plant emergence and survival data collected from a field study which focused on overcoming seed dormancy. Seed dormancy can present a challenge within a restoration scenario where rapid establishment is required. Soaking seeds in gibberellic acid (GA3) can overcome dormancy and increase germination but this treatment may not be effective outside the laboratory. An easier and potentially more effective method to apply this hormone is to coat seeds with a GA3-impregnated polymer, which provides a slow release of GA3. Seed dormancy can also be mitigated by creating a favorable microsite with …
Use Of Plant Growth Regulators To Expand The Period Of Sagebrush Seed Germination And Reduce The Risk Of Restoration Failure: Laboratory Trials, Chelsea Elizabeth Keefer
Use Of Plant Growth Regulators To Expand The Period Of Sagebrush Seed Germination And Reduce The Risk Of Restoration Failure: Laboratory Trials, Chelsea Elizabeth Keefer
Theses and Dissertations
Seed germination during unhospitable environmental conditions can be a major barrier to direct seeding efforts in dryland systems. In the sagebrush steppe, Artemisia tridentata Nutt. ssp. wyomingensis and Artemisia arbuscula are important shrub species that are being used in restoration, but seeding success is highly sporadic due to inter-annual and intra-seasonal weather variability. Altering and expanding the period of germination, as a form of bet-hedging, may improve plant establishment. Our objective was to determine if we could expand the period of germination using plant growth regulators (PGRs) applied in a conglomerated seed coating treatment. In a laboratory study, the seed …
Effects Of Abscisic Acid (Aba) On Germination Rate Of Three Rangeland Species, Turmandakh Badrakh
Effects Of Abscisic Acid (Aba) On Germination Rate Of Three Rangeland Species, Turmandakh Badrakh
Theses and Dissertations
Seeds sown in the fall to restore sagebrush (Artemisia spp.) steppe plant communities could experience high mortality when they germinate and seedlings freeze during the winter. Delaying germination until the risk of frost is past could increase seedling survival. We evaluated the use of abscisic acid (ABA) to delay germination of Elymus elymoides, Pseudoroegneria spicata, and Linum perenne. The following treatments were applied: uncoated seed, seed coated with ABA at 2.2, 4.4, 8.8, 13.2, and 17.6 g of active ingredient kg-1 of seed, and seed coated with no ABA. The influence of seed treatments on germination were tested at five …
