Due to the outstanding importance of oxidative stress tolerance
in stress physiology (Apel and Hirt, 2004), an overwhelming
amount of studies have evaluated the response of crops’ antioxidant
systems to environmental stresses. However, most of these
studies dealt with the photosynthetic tissue during the seedling or
early vegetative growth stages of crops, because these are critical
phases in plant survival and yield formation. Such reports are not
considered in this review.
