Ethylene was the most effective abscission accelerant examined, with decreasing activity shown by propene, carbon monoxide, acetylene, vinyl fluoride, 1-butene, and 1,3-butadiene. Carbon dioxide inhibited abscission, but its effect was overcome by ethylene. Oxygen was required for abscission as an electron acceptor for respiration and not as a potentiator or activator of the ethylene attachment site. The molecular requirements for abscission were similar to those shown by other workers for other biological processes under the influence of ethylene.
乙烯是研究过的最有效的脱落促进剂,丙烯、一氧化碳、乙炔、氟乙烯、1-丁烯和 1,3-丁二烯的活性依次降低。二氧化碳抑制脱落,但它的作用被乙烯所克服。脱落需要氧气作为呼吸的电子受体,而不是作为乙烯附着位点的增效剂或激活剂。脱落的分子要求与其他工作者在乙烯影响下研究的其他生物过程的要求相似。
