Struve, Daniel K.; Moser, Bruno C. published an article on January 31 ,1984. The article was titled 《Auxin effects on root regeneration of scarlet oak seedlings》, and you may find the article in Journal of the American Society for Horticultural Science.Quality Control of Potassium 4-(1H-indol-3-yl)butanoate The information in the text is summarized as follows:
Dipping root systems of scarlet oak seedlings (Quercus coccinea) in indol-3-butyric acid K salt (K-IBA) [60096-23-3], 2,4-D [94-75-7], 2,4,5-T [93-76-5], 2,4,5-trichloropropanoic acid [93-72-1], β-naphthoxyacetic acid [120-23-0], and NAA [86-87-3], induced a 6-fold increase in adventitious root regeneration, as compared to control seedlings. Time to first root initiation was increased and root elongation rate was decreased for auxin-treated seedlings relative to untreated controls. Under field conditions, 1-yr-old seedlings treated with NAA, at 3000 mg/L, or K-IBA, at 1000 or 3000 mg/L, regenerated more roots and developed greater root length than did control plants. Toothpicks impregnated with a 1000 mg/L K-IBA solution and inserted into tap roots stimulated an 18-fold increase in root length, as compared to control seedlings. In the part of experimental materials, we found many familiar compounds, such as Potassium 4-(1H-indol-3-yl)butanoate(cas: 60096-23-3Quality Control of 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.Quality Control of Potassium 4-(1H-indol-3-yl)butanoate
