Plant growth regulators part 35 benzodiazolylalkyl carboxylic acids benzotriazolylalkyl carboxylic acids benzothiazolylalkyl carboxylic acids and some related compounds

Seven pairs of optically active propionic acids containing heterocyclic nuclei were studied with respect to their growth effects on oat coleoptile cylinders, wheat roots and flax roots. All are mainly anti-auxinic but traces of auxin activity may be present in some of the D-forms. L-benzimidazolyl-2-thiopropionic acid shows very high anti-auxin activity in the root tests, while the activity in the oat coleoptile cylinder test is comparatively much weaker.
