Abstract
A SUBSTANTIAL number of reports has appeared indicating failure in the detection of indolyl-3-acetic acid (IAA) in some plant tissues1–5. Luckwill1 and Luckwill and Powell2 were unable to detect IAA in the leaves, seeds and flesh of several varieties of apples. Working with McIntosh and Cortland varieties under various storage conditions, we have detected a substance in the fruit the chromatographic behaviour and colour reactions of which are identical with IAA.
