The elongation response of excised 15-mm sections of etiolated rye coleoptiles to added auxin (IAA, concentration: 10 μM). One hour after cutting (= time zero), batches of ten coleoptile sections were either incubated in the absence (−IAA) or presence (+IAA) of auxin and the elongation response recorded. Data represent means of six independent experiments. The standard errors of the means (± SEM) are not shown because they are smaller than the size of the symbols. v = average rate of growth.
