Summary

Relative growth rates in swards of vernalized plants of perennial ryegrass were one and a half times as great as those found in swards of comparable non-vernalized material. This difference was associated with changes in the distribution of the products of photosynthesis and differences in the scale of losses of dead matter. Changes in sward geometry appeared to be of less importance.
