Synopsis

Synopsis

The roots of tobacco plants were subjected to a wide range of simulated aeration conditions. In general nutrient uptake remained relatively constant until oxygen concentrations dropped below 10%. However, a concentration of 5% carbon dioxide apparently stimulated phosphorus uptake.
