Maize and Leaf Growth

Our ‘corn’ project addressed the physiological basis of high yield in newer corn hybrids. As new varieties have been produced by plant breeding programs, they have been selected for tolerance to high density plantations. We looked for mechanisms by which newer varieties withstand density stress. This “micro-evolution” study compared older and newer genotypes, and looked for subtle physiological changes that render newer plants less sensitive to crowded conditions.
