Abstract
Root applications of 9.0 μ M 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine) to soybean plants ( Glycine max (L.) Merr., var. Chippewa) for 4 hr significantly reduced their transpiration rates. Similar reductions in transpiration rate were elicited by foliar applications of 900 μ M. All atrazine treatments that reduced transpiration prevented dry weight accumulation by the plants and increased plant hydration. Root additions of glucose to de-rooted plants treated with atrazine had no influence on the transpiration reduction due to atrazine treatment but caused an increase in dry weight accumulation. There was a rapid accumulation of 14 C-atrazine in the roots of the soybean plants from the culture solution with subsequent movement to the leaves. Leakage of 14 C-atrazine out of the roots into the water medium after treatment termination was observed.
