Abstract
SEVERAL investigators have recently pointed out the accelerating effect of 2 : 4-dichlorophenoxyacetic acid (2,4-D) on the destruction of auxin in dicotyledonous plants1–3. In addition, one group3 has revealed that the opposite effect prevails in oat coleoptile sections, that is, 2,4-D effects a prevention or ‘sparing action’ of the previously reported destruction of indolylacetic acid in oat coleoptiles4.
