1981/03/03: Jeff Dawson to George Ware (3.38659)
Date: March 3 1981Creator: Dawson, Jeffrey O.
Type: Document
Description:Letter from Jeff Dawson, Assistant Professor of Forestry at University of Illinois at Urbana-Champaign to George Ware discussing an outline of proposed research concerning the low soil oxygen tolerance (with mention of ethanol and flood tolerance) of maple and oak trees.
Enclosed with letter
An Ethanol Tree-Seedling Assay: A Potential Method to Screen Trees for Tolerance to Low Soil Oxygen Conditions Resulting from Soil Compaction and Paving. Review of current literature and proposal for two experiments to examine oxygen deficiency and ethanol tolerance in tree seedling roots. The results would be used in the creation of an tree survivability index which would be of use in flood prone areas or compacted urban and recreational sites.
