Cation Concentration in Post-Imbibed Winterfat Seeds as Influenced by Imbibition Temperature

Project Description

Winterfat prefers cold-weather seedings (late fall, early spring), and there is a correlation between reduced seedling vigor and imbibition at warmer temperatures. This study looked at whether imbibition at warm temperatures damages winterfat seed membranes, as well as whether there is an increase in cation loss due to potential membrane damage.

County: Laramie County, WY

Project Sites

  • Cheyenne, Wyoming

Goals and Targets

Primary Goals:

  • The projects collected in this database contain summaries and conclusions from a wide variety of papers regarding restoration research relevant to the Colorado Plateau. Using the conservationregistry.org search engine, search for a particular species (i.e. Atriplex canescens, fourwing saltbush), type of study (i.e. common garden, reciprocal transplant) or keyword (i.e. ecotype, grazing) in order to view the citations, summaries and conclusions of relevant papers.

Targeted Habitats:

  • Forests and Woodlands
  • Human Habitats
  • Shrublands and Grasslands

Targeted Species:

  • Winter-fat Krascheninnikovia lanata

Outcomes

Is the success of this project's actions being monitored? No/Unknown

Lessons Learned and/or Suggestions for Similar Activities
Conclusion(s): Winterfat seeds did not appear to sustain membrane damage when imbibition occurred at high temperatures (i.e. 20° C), and as a result, no cation-loss was detected. Although winterfat will have reduced seedling vigor when planted during warm periods, the reason for this is not yet known.

Any Additional Information About The Project
Booth later hypothesized that mitochondrial damage occurs when seeds are not stored at sufficiently low temperatures (-18° C), and the seeds in this study were stored at 5 ° C. See Booth (1999) [project #100782] for more information. A link to this project is under "Related Projects" on the right hand side of the page.
