| Abstract:
The relationship between ethylene and ripening and the role of other factors in controlling ripening are briefly discussed. Determination of the concentration of ethylene in the internal air spaces using vacuum extraction techniques consistently gives much higher figures than are obtained by analysis of gas from an internal cavity such as the lacuna of broad bean. One possible interpretation of this result is that ethylene may not be able to diffuse freely between the cell and the adjacent air space and therefore, that the actual 'internal' concentration of ethylene in the cell may be quite different to that in the tissue air spaces. A rapid metabolism of ethylene to ethylene oxide has been described and the possible significance of this is discussed. | |
