The following experiments investigated the levels of gibberellin-like activity in bleeding sap of grape vines, an attempt was made to relate these levels to the amounts of activity detectable in other parts of the plant.

Calculations on the rate of gibberellin movement from the roots seemed to be compatible with levels of activity in the leaves, although these levels could also be a reflection of the general gibberellin level in the plant.

The relevance of the findings is discussed.
