A System for Dynamic Analysis in Biological Systems with Carbon-11

An integrated approach to the study of effects of environmental factors on plants is described The system relies on the continuous labelling and measurement of naturally occurring tracer activity as it courses through the plant These features allow the investigation of the magnitude of the photosynthate distribution, the transport times of photosynthates, and the dynamic response of the distribution to environmental factors A host of ecologically, agriculturally and genetically important questions can be answered with this technique, including the consequences of increased CO2 concentration in the atmosphere, and other environmental effects.
