1940 W. R. Fearon Introd. Biochem. (ed. 2) xxiv. 446 The effect of the phytohormones is non-specific as regards species.

1959 L. J. Audus Plant Growth Substances (ed. 2) i. 16 In the past a rigid distinction has been made between..‘synthetic growth-regulating substances’ and ‘natural phytohormones’.

1971 Nature 4 June 332/1 Jump suggested that a phytohormone produced by A[ureobasidium] pullulans (Dematium pullulans) may have been responsible for forking in red pine.

1990 Org. Gardening Nov. 52/2 Apparently, the phytohormones auxin, cytokinin and gibberellin in kelp products such as SeaMix, Sea Crop and FoliaGro stimulate the increased yields.
