Drought stress is a key restraint to crop productivity worldwide, specifically in arid and semi-arid regions. It can lead to physiological and biochemical changes ultimately leading to oxidative burst. Finger millet, often considered an orphan crop, is known to be drought tolerant and a rich source of calcium. In the present work, responses of four finger millet varieties, at seedling stage, to PEG-induced moderate and extreme water stress have been documented. Physiological and biochemical aspects were studied based on which the finger millet varieties were designated as drought tolerant and sensitive. |
