Morphological and Physiological Responses of Rice (Oryza sativa) to Limited Phosphorus Supply in Aerated and Stagnant Solution Culture

Rain-fed lowland rice commonly encounters stresses from fluctuating water regimes and nutrient deficiency. Roots have to acquire both oxygen and nutrients under adverse conditions while also acclimating to changes in soil-water regime. This study assessed responses of rice roots to low phosphorus supply in aerated and stagnant nutrient solution.
