Auxin Activity of Certain Oximes

Abstract

IN auxin studies on compounds not possessing a carboxyl group Wain found, in this laboratory, that 2 : 3 : 6-trichlorobenzaldoxime exhibits activity as a plant growth regulating substance. At his suggestion other oximes were investigated by the writer and Mr. P. Cozens, and 3-indolylacetaldoxime and 2 : 4-dichlorophenoxyacetaldoxime were also found to be active (Table 1). Further work was then undertaken to determine whether these aldoximes are active per se or if they undergo metabolism in plant tissues to yield active substances.
