Electrical Conductivity as a Measure of Low Temperature Stress in Southwest Maize Land Races.

Ann M. Rossi, Deborah Muenchrath, and Allen Knapp. Iowa State University, Iowa State University, Agronomy Dept., Ames, IA 50011-1010

Early season low temperature stress can reduce maize emergence and growth, increasing production costs. It has been shown that selection for low temperature stress tolerance exists in adapted maize populations, and it is also likely that some maize land race accessions carry genes for improved low temperature stress tolerance. This poster reports assessments of low temperature stress tolerance in three accessions as determined by leaf electrical conductivity and plant dry weight. Stress responses were measured prior to and following seven days of cold stress, and after a six day recovery period. The value of these screening tools will be discussed.
