Reducing the level of endogenous ethylene in detached Shamouti oranges (Citrus sinensis L. Osbeck) by means of subatmospheric pressure did not alter the rate of chlorophyll destruction and color changes during the first 8 days after harvest in the presence or absence of exogenous ethylene. Reducing the activity of ethylene by means of CO(2)-known to be a competitive inhibitor for ethylene-inhibited chlorophyll destruction and color change in Shamouti oranges ventilated with ethylene, but had no effect on these processes in the absence of applied ethylene. The evidence presented indicates that endogenous ethylene may not be the primary inducer for the natural color change in detached Shamouti oranges.
通过减压降低沙莫蒂甜橙（Citrus sinensis L. Osbeck）离体果实中的内源乙烯水平，在收获后的前8天，无论有无外源乙烯，均不会改变叶绿素的破坏速率和颜色变化。通过CO₂降低乙烯活性——已知CO₂是乙烯的竞争性抑制剂——可抑制用乙烯通风处理的沙莫蒂甜橙的叶绿素破坏和颜色变化，但在未施加乙烯的情况下对这些过程没有影响。所提供的证据表明，内源乙烯可能不是沙莫蒂甜橙离体果实自然颜色变化的主要诱导因素。
