Abstract:Drought is a major challenge, affecting rice at the morphological, physiological, biochemical and molecular levels. This study was conducted to compare eight cultivars of rice (Oryza sativa L.) for drought tolerance based on some morphological, physiological and molecular tests at the seedling stage. Drought stress was imposed by four levels of polyethylene glycol (PEG) 0, 5, 10 and 15% for 5 days. After 5 days, where seeds of all concentrations were watered daily with tap water for 21 days, plant samples were… Show more
