Abstract
GIBBERELLINS and auxins are both capable of enhancing the growth of plant stems1. It has been suggested2–4, however, that the gibberellins are not directly involved in this process but act, instead, by modifying the concentration of endogenous auxin in the stems. This suggestion is supported by the fact that in certain tissues gibberellins can cause an increase in the synthesis2,3 or a decrease in the destruction4 of auxin.
