Abstract

Abstract The effects of 2,4‐Dichlorophenoxyacetic acid on the growth rate, chemical composition, 14C‐2,4‐dichlorophenoxyacetic acid and 45Ca2+ uptake by Rhizobium sp. M 4 able to nodulate Arachis hypogaea were determined. Cellular growth was diminished by the presence of 10−3 M 2,4‐dichlorophenoxyacetic acid in the medium. Alterations in cellular chemical composition, in 14C‐2,4‐dichlorophenoxyacetic acid and in 45Ca2+ uptake were found.
