Abstract
Barley was grown at a range of oxygen concentrations (0.5–9 mg l−1), in nutrient solutions. Growth of both shoots and seminal roots was restricted by O2 concentrations lower than 2–3 mg l−1) but nodal root growth was not. Root porosities were increased even at those O2 concentrations which did not restrict growth, and were inversely proportional to the protein levels of the roots. Sugar concentrations increased appreciably only at those O2 concentrations which also restricted growth.Keywords
