Resumen

La adaptación al cambio climático es un desafío ya que los rendimientos del maíz muestran una mayor sensibilidad a la sequía, a pesar de las ganancias generales de rendimiento. Los cambios agronómicos, como las densidades de siembra más altas, aumentan los rendimientos promedio, pero no la resiliencia al estrés por sequía.

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
