苹果(Malus home tica Borkh.)CV。用不同浓度的乙烯处理(通常为48h)，以确定它们对发育阶段的反应。记录的主要反应是乙烯减少了个体果实快速乙烯产生(DEP)的开始时间。在发育早期，低浓度的乙烯几乎没有影响，但DEP逐渐减少，浓度最高可达107mm3·m-3。随着果实接近自然开始的快速乙烯合成，102和103mm3m-3的浓度变得越来越有效。增加固定浓度处理的持续时间会成比例地减少DEP。采收后延迟48h处理对DEP与乙烯浓度的关系影响不大。尽管在果实发育过程中，果实对气体扩散的抵抗力有所增加，但这种抵抗力始终不足以影响浓度与反应的关系。
Fruits of apple (Malus domestica Borkh. cv. Cox''s Orange Pippin) were treated with various concentrations of ethylene usually for 48 h to determine their response in relation to stage of development. The main response recorded was the reduction by ethylene of the delay in onset of rapid ethylene production (DEP) in individual fruits. Early in development low concentrations of ethylene had little effect but DEP was progressively reduced by concentrations up to 107 mm3 m-3. As the fruit approached the natural onset of rapid ethylene synthesis concentrations of 102 and 103 mm3 m-3 became increasingly effective. Increasing the duration of treatments with a fixed concentration reduced DEP proportionately. Delay after harvest in applying a 48 h treatment had little effect on the relation between DEP and concentration of ethylene applied. Although resistance to diffusion of gas in fruits increased during fruit development this resistance was never large enough to affect the relation of concentration and response.
