NEW METHODS FOR EFFECTING WATERTIGHT SEALS ON CORN ROOTS,
Abstract
Two effective methods of sealing corn roots into capillary glassware are described. One involves only a slight pressure on the root but cannot withstand hydrostatic pressures across the seal in excess of 15 cm of water. The second, capable of withstanding 2 meters of hydrostatic pressure, requires a melted sealing compound which can raise the root epidermis to temperatures between 50 and 56 C for about 2 seconds. Experiments using radioactive tracers have demonstrated that both seals effectively prevent ionic movement external to theroot proper and that the heat-sealing process does not alter the root's absorption-transport capacity.
