Auxins

In normally growing plants, the auxin phytohormones are responsible for phototropism and apical dominance. They also influence abscission of blooms, leaves, and fruit, making them valuable tools in bringing fruits and horticultural products to market. Auxins are widely used in plant propagation and tissue culture. Cuttings are routinely treated with auxins to induce root formation. In tissue culture, auxins are balanced with cytokinins for full morphogenesis. We offer naturally occurring as well as synthetic auxins. The potent natural auxin, 3-indoleacetic acid (IAA), is available in both acid and salt form. Its metabolic precursor, indole-3-butyric acid (IBA), is more stable in some instances. Naturally occurring phenylacetic acid is weaker than IAA, but may be more abundant in nature. Synthetic auxins, such as 1-naphthaleneacetic acid (NAA) and 2-4-dichlorophenoxyacetic acid (2,4-D) are potent and less expensive alternatives to IAA. 2,4-D is very often the auxin of choice in inducing callus and in keeping cells in the dedifferentiated state. Most of our auxins are available as acids or as salts.
