Abstract
Abstract Cured storage roots of sweet potato [Ipomoea batatas (L.) Lam. cv. Centennial] were wounded and recured for 12 days with or without 2,5-norbornadiene, AOA, or CoCl2 treatments. Ethylene production, wound lignification, and wound periderm formation were measured 0, 3, 6, 9, and 12 days after wounding. Ethylene production preceded wound lignification and wound periderm formation by 24 to 48 hr, respectively. Blocking ethylene action with 2,5-norbornadiene increased ethylene production, blocked wound periderm formation for up to 12 days, and strongly suppressed and delayed lignification. Blocking ethylene synthesis with AOA or CoCl2 decreased ethylene production to 10% of the control. Lignification and wound periderm formation were also suppressed and initiation delayed. These results suggest that ethylene is involved in lignification and periderm formation in wounded sweet potato roots. Chemical names used: bicyclo[2.2.l]hepta-2,5-diene (2,5-norbornadiene); (aminooxy) acetic acid (AOA).
