Abstract

Experiments with C14-labeled bicarbonate demonstrate that organic products of photosynthesis are transported through the stipe tissue of Macrocystis. Depending upon conditions, not all of which have been fully ascertained, the direction of transport may be either predominantly apical or toward the base of the plant.
