Inhibition of Limonoid Biosynthesis by Auxins. Auxins are potent inhibitors of nomilin biosynthesis in citrus seedlings (31). For instance, up to 91% inhibition was observed when 10 ppm of indoleacetic acid was fed to the stem of a lemeon seedling two days prior to and two days following feeding of 25 pCi of 14-C acetate (Table 1). Other auxins tested include 1-naphthaleneacetic acid (NAA), indolepropionic acid, indolebutyric acid, 3-indole acetonitrile, ethyl indole-3-acetate, 3-indoleacrylic acid, 3-(2-hydroxyethyl)indole, indole-2-carboxylic acid and 2,3,4-trichlorophenoxyacetic acid. They were all very effective. 

USE Indolebutyric acid suitably diluted (Hormodin, Sera-dix) is used for promoting and accelerating root formation of plant clippings.

The major natural auxin is indole-3-acetic acid (lAA) [42]. A number of related compounds exist in plants, including indolebutyric acid and indoleacetonitrile (Fig. la). These related compounds are active primarily when first converted to lAA [42]. In addition, there are a series of LAA conjugates with sugars and amino acids [43]. Some of these may be detoxification products, but others may be reservoirs of releasable lAA, especially in seeds. Phenylacetic acid (Fig. la) has auxin activity, and exists in sizable amounts in a few plants such as tobacco [42], but it is unclear that this compound actually moves from one part of a plant to another. In addition to the natural auxins, a whole host of synthetic auxins are known. The most widely used are a-naphthaleneacetic acid (NAA) and 2,4-dichlorophenoxyacetic acid (2,4-D) (Fig. la). 

The microbalance was found to give a linear response to template at concentrations between 10 and 200 nM. The selectivity of the imprinted and nonimprinted polymers was tested with the analogous compounds indolebutyric acid and indole ethanol. The results obtained are given in Table 1.
