| Abstract |
Alfalfa plants were hydroponically grown in environmental growth chambers in which they were continuously exposed to tritium throughout growth. All segments of the environment were in equilibrium with respect to the specific activity of tritium. The tritium content in plant organic matter was about 22 percent lower than in the plant free water or rooting solution. Under conditions of low transpiration, there was a higher concentration (about 1.8) percent of tritium in the leaves than in the stems and rooting solution. This is thought to represent the result of fractionation during transpiration. |
