Another area of wheat research in its infancy, is the specific ways in which weather impacts wheat. While most growers are certainly familiar with soil moisture, humidity and growing degree days, there are many weather-related impacts throughout the year.
In this section, the researcher looked at overwintering effects and specifically the impacts of ice encasement on overall winter hardiness.
Research by Dr. Emily Holm, Dr. Eric Olson and Dennis Pennington
This one-year project sought to look at negative overwintering impacts on wheat at the cellular level, beyond recent research on low temperatures or freeze-thaw cycle impacts on wheat. Holm sought to explore wheat cells’ tolerance to abnormally high and low winter temperatures and fluctuations therein.
Holm postulated that winter wheat’s hormonal responses to ice encasement and ensuing winter hardiness (or lack thereof), could reveal metabolic and physiological pathways that could be exploited to improve wheat’s resilience over winter. And further whether fall-applied plant growth regulators (PGRs) could improve wheat’s winter survival and health, and whether the industry would accept this treatment.
