Abstract

Carbon14 carboxy labeled 2,4-D with varied amounts of Tween 20 (polyoxyethylene sorbitan monolaurate) was applied to excised Kalmia angustifolia L. (Ericaceae) leaves and, after an absorption period, the radioactivity of the dried ground leaf tissue was measured by counting. Entry rate of 2,4-D into recently formed leaves decreased with increase in Tween 20, within the range of 2,4-D/Tween 20 ratios used (roughly 5/1 to 0.5/1). Entry rate of 2,4-D into older leaves increased with increase in Tween 20.
