Abstract Metabolism of 12 synthetic d, l-chlorophenylalanines has been examined in several crop and weed plants. Twenty-five gram samples of excised shoots or leaves of bushbean, soybean, corn, pigweed, lambsquarters and giant foxtail were allowed to metabolize 10− 4 M solutions of the d, l-chlorophenylalanines for 24 hr in continuous light. The plant samples were then extracted in 80% methanol and the soluble acidic metabolites fractionated into ...
