Blythe, Eugene K.; Sibley, Jeff L.; Tilt, Ken M.; Ruter, John M. published an article in Journal of Environmental Horticulture. The title of the article was 《Auxin application to stem cuttings of selected woody landscape plants by incorporation into a stabilized organic rooting substrate》.Name: Potassium 4-(1H-indol-3-yl)butanoate The author mentioned the following in the article:
Stem cuttings of Buxus sinica var. insularis “”Wintergreen””, Elaeagnus × ebbingei, Ficus benjamina, Gardenia augusta “”Radicans””, Ilex glabra “”Nigra””, Ilex vomitoria “”Nana””, Juniperus conferta “”Blue Pacific””, Ternstroemia gymnanthera, and Trachelospermum asiaticum were inserted into a stabilized organic rooting substrate (plugs comprised of peat and a polymer binder) that had been soaked in water, aqueous solutions of K-IBA (15 to 75 ppm), or K-IBA + K-NAA (15 ppm + 7.5 ppm to 60 ppm + 30 ppm). Rooting and initial shoot growth responses were compared with cuttings receiving a basal quick-dip in K-IBA (1000 ppm) or K-IBA + K-NAA (1000 ppm + 500 ppm). Rooting percentage, number of roots per rooted cutting, and total root length per rooted cutting for cuttings rooted in auxin-treated plugs were similar to or greater than cuttings receiving a basal quick-dip; lesser results were obtained in a few cases with K-IBA + K-NAA. Percent of rooted cuttings with new shoots and shoot length per rooted cutting for cuttings rooted in plugs treated with K-IBA were mostly similar to cuttings receiving a basal quick-dip in K-IBA, while cuttings rooted in plugs treated with K-IBA + K-NAA exhibited similar or lesser results compared to cuttings receiving a basal quick-dip in K-IBA + K-NAA. In the experimental materials used by the author, we found Potassium 4-(1H-indol-3-yl)butanoate(cas: 60096-23-3Name: Potassium 4-(1H-indol-3-yl)butanoate)
Potassium 4-(1H-indol-3-yl)butanoate(cas: 60096-23-3) is auxin-family plant hormone, and is thought to be a precursor of indole-3-acetic acid (IAA) the most abundant and the basic auxin natively occurring and functioning in plants. IAA generates the majority of auxin effects in intact plants, and is the most potent native auxin.Name: Potassium 4-(1H-indol-3-yl)butanoate
