ABSTRACT
This chapter discusses physiological, biochemical and molecular factors associated with the recuperative ability of grass species from drought stress by addressing the questions on how drought-resistance traits may affect post-drought recovery, and identifying the specific mechanisms involved in post-drought stress recovery that enable plants to regenerate or re-establish and restore normal functions. Drought stress is an important environmental factor that can negatively impact the growth and development of many plant species. A major area of post-drought recovery regrowth potential involves the use of carbohydrate reserves that are stored within tissues of certain plant organs during drought, which provides a recovering plant with the necessary resources for rapid regrowth. One of the unfortunate effects of drought stress is oxidative stress, or the increased production of harmful reactive oxygen species within plants, which include radicals such as superoxide or hydroxyl, and non-radicals such as hydrogen peroxide and singlet oxygen.
