Molecular Mechanisms of Chilling-Induced Oxidative Stress Injury and Tolerance in Pre-Emergent Maize Seedlings
The adversities of environmental stresses, such as low temperature, can severely affect the productivity of various chilling-sensitive crops including maize (Greaves, 1996). Because maize is a chilling-sensitive crop, exposure to chilling stress during the stages of germination and early seedling growth can be detrimental to stand establishment. Planting in early spring to take advantage of more optimal temperatures and summer rainfall and to avoid hot, dry summer periods during pollination and fertilization, is one of the most desired agronomic practices in maize (Stewart et al., 1990). Therefore, molecular, genetic and physiological characteristics that improve chilling tolerance are of immense interest to maize producers.
