乙烯提高了所测试的十个甘薯品种（Ipomoea batatas(L.) Lam.）根盘中的九个的过氧化物酶活性。乙烯处理后四小时观察到的增加部分被二氧化碳克服。这种增加被放线菌素 D 和放线菌酮抑制，表明蛋白质从头合成。聚丙烯酰胺凝胶上的电泳分离表明出现了两个新的过氧化物酶带。豆叶柄外植体中的过氧化物酶活性位于分离层周围。乙烯导致外植体叶柄部分过氧化物酶活性小幅增加。酚类物质对脱落没有影响，这与它们作为生长素氧化酶辅助因子的作用一致，表明生长素氧化酶在彩叶草的脱落中不起作用。脱离区外植体。
Ethylene increased the peroxidase activity of nine out of ten varieties of sweet potato (Ipomoea batatas(L.) Lam.) root disks tested. The increase which was observed four hours after ethylene treatment was partially overcome by carbon dioxide. The increase was inhibited by actinomycin D and cycloheximide, indicatingde novoprotein synthesis. Electrophoretic separation on polyacrylamide gels indicated the appearance of two new peroxidase bands. Peroxidase activity in bean petiole explants was localized around the separation layer. Ethylene caused a small increase in peroxidase activity in the petiolar portion of the explant. Phenolic substances had no effect on abscission consistent with their proposed roles as cofactors for auxinoxidase, indicating that auxin‐oxidase does not play a role in abscission ofColeus blumeiBenth. abscission zone explants.
