Abstract

In 1935, Thimann and Koepfli reported the synthetic preparation of the auxin indole-3-acetic acid (IAA), a naturally occurring substance that had recently been found to have root-forming properties, and demonstrated its practical use in stimulating root formation on cuttings.
In that same year, Zimmerman and Wilcoxon reported that the synthetic auxins indole-3-butyric acid (IBA; now known to occur naturally in plants) and 1-naphthaleneacetic acid (NAA) were more effective than IAA for rooting cuttings.
Indole-3-butyric acid and NAA are presently the most widely used auxins for promoting root formation on stem cuttings.
Auxin treatments are commonly used in commercial plant propagation to increase overall rooting percentages, hasten root initiation, increase the number and quality of roots, and encourage uniformity of rooting.
Commercial root-promoting products (rooting hormones) are available in various formulations: liquid concentrates, water-soluble salts and tablets, gels, and powders (talc).
