Aberg, Borje published the artcilePlant growth regulators. XII. Monosubstituted phenoxyacetic acids, COA of Formula: C12H16O3, the publication is Kgl. Lantbruks-H?gskol. Ann. (1957), 375-92, database is CAplus.
cf. C.A. 49, 10443h. Tests of the effect on growth were made on flax seedling roots, wheat seedling roots, and oat coleoptile cylinders as previously described (cf. ?berg, Chemistry and Mode of Action of Plant Growth Substances, London, 1956, pp. 93-116). The results were not consistent in some cases. Initial inhibition that could be relieved by indoleacetic acid (IAA) was shown by 2-substituted phenoxyacetic acids at low concentrations and stimulation of the oat cylinders at high concentrations High IAA-like activity by 2-Me- and 2-iso-Pr-compounds contrasted with low of 2-methoxy and 2-NO2-compounds Low concentrations of 3-Cl-, 3-Br-, 3-Me-, 3-MeO- and 3-NO2-compounds stimulated growth of wheat roots. Growth of flax roots was inhibited, which could be relieved by ¦Á-(1-naphthylmethylthio)propionic acid. The IAA-like effect of the 4-substituted compounds grew less with increasing size of the substituent. Auxin effects may be caused at high concentrations by the same substance that causes antiauxin effects at low concentration
