1. Determine the degree of chilling tolerance of agronomically superior corn. 2. Quantifying the effects of waterlogging on emergence, physiology, and root traits. 3. Assess the biochemical response of stress-tolerant and sensitive corn.
Growth Chamber studies will be conducted using commercially grown high-yielding corn genotypes in the US midsouth region. Corn genotypes will be exposed to low vs optimum temperatures and waterlogging vs optimum moisture conditions to identify stress-resilient corn at germination, emergence, and early vegetative growth stages. Identifying stress-resilient corn at the vegetative stage offers an opportunity to overcome production challenges and efficiently utilize early summer rainfall for growth and development.
