In the sequential response to plant growth regulators in young elongating tissue from peas and wheat the peak of sensitivity to 24‐epi‐brussinolide (1 μM) occurs after those of gibberellin and cytokinin and begins before that of auxin in isolated wheat ( Triticum vulgare L. ev. Egret) coleoptiles aged from 21‐96 h. In dwarf pea ( Pisum sativum L. cv. Greenfeast) segments, the peak of sensitivity also lies between those of gibberellin and auxin, and it also occurs before sensitivity to auxin in sections from first leaves of wheat. All the leaf sections and all but the most mature coleoptiles and pea segments were sensitive to fusicocein (1 μM).
