The deficiency of oxygen concentration in root environment linked to waterlogging conditions caused important injuries for plants. These effects could be reproduced by oxygen deficient nutrient solution. This bibliographical synthesis has been centered on experimental results obtained on plants cultivated in soilless culture. This review paper presents a methodology used to study oxygen depletion in a nutrient solution and to calculate root respiration rates. The main factors influencing root respiration are reviewed as well as the consequences of oxygen deficiency on roots and shoots functioning. This study would not be complete without some information on the main mechanisms of plant adaptation to oxygen deficiency.
