Abstract
Increased ethylene synthesis was rapidly induced throughout the apical meristematic region of etiolated seedlings of Pisum sativum L., cv. Alaska by cuts made 1 centimeter from the apical hook. The wound signal was transmitted at about 2 millimeters per minute. Accumulation of substance(s) at the cut surfaces of excised sections, as the result of interrupted translocation, did not initiate or significantly contribute to wound-induced ethylene synthesis, nor was the cut surface the site of enhanced ethylene synthesis. Cutting subapical sections into shorter pieces showed that cells less than 2 millimeters from a cut surface produced about 30% less ethylene than cells greater than 2 millimeters from a cut surface.This publication has 8 references indexed in Scilit:
