摘要
The plant growth-regulating activity of all the mono- and di- chloro-substituted phenylacetic acids, together with the 2:3:6-trichloro- derivative, has been determined in the wheat cylinder, pea segment and pea curvature tests. Each of these compounds showed activity, the 2:3-dichloro- and the 2:3:6-trichloro-derivatives being extremely active. The 3:5-dichloro- acid was inactive in the wheat test but showed moderate activity in the pea tests. All these findings are discussed in relation to the plant growth-regulating activity of corresponding benzoic and phenoxyacetic acids.
