    Evaluation of physiological and morphological basis for drought resistance in maize and sorghum
    (2004) Takele, Abuhay; Farrant, Jill M
    Drought stress is often the most limiting factor to maize and sorghum production in the semi-arid areas. This study evaluates the physiological (water relations, gas exchange characteristics, membrane leakage), biochemical (antioxidant protection mechanisms and photosynthetic pigment compositions) and seed viability and quality response of maize (cv Melkassa-2) and sorghum cv Macia) after exposure to and recovery from pre and post-flowering dehydration in plants grown in a controlled environment growth chamber under constant environmental conditions (12/12h day/night, 28-32/17 °c day/night temperature, 60-80% RH and PPFD of 1200-1400 umol m-2 S-1), at the Department of Botany, University of Cape Town.
