Segment test to study the action of the phytohormone auxin (IAA) in grass coleoptiles. Growth response of excised mesocotyl- and coleoptile segments (10 mm in length) after addition of IAA (10 μM, 24 h) (a) and short-term growth response, measured using the same plant material (b) (25 °C, darkness; incubation medium: distilled water); n=12 replicates each. The error bars are smaller than the size of the symbols
