M c C lure , T. T. (Plant Pest Control Division, ARS, USDA, Washington, D. C.) Chlorogenic acid accumulation and wound healing in sweet potato roots . Amer. Jour. Bot. 47(4) : 277—280. Illus. 1960.–Chlorogenic acid accumulation in cells adjacent to a wound occurs before suberization and wound‐periderm formation. Suberization during wound healing was highly correlated with chlorogenic acid accumulation and with wound‐periderm formation. The possible role of chlorogenic acid as a source of chemical units for suberization is suggested. Histochemical tests indicate that suberization during wound healing may be a form of lignification. Over 5 times as much lignin was found by chemical analysis in the tissues of healed surfaces as in controls.
