Sensitivity (A), responsivity (B), and dependency (C) of the MdACO1as apples to exogenous ethylene. Sensitivity and responsivity was determined as the ethylene concentration required for a 50% response and the rate of change, respectively, using non-linear regression and a logistic function. Ethylene dependency (%) was calculated as the difference between the 0 μl l−1 and 1000 μl l−1 ethylene treatments divided by the 1000 μl l−1 ethylene treatment, and multiplying by 100 to give a percentage: 0%=ethylene independent, 100%=ethylene dependent.
