Physiology
* Respiration rate at 5°C. Low = <5ml.kg-1.h-1; Moderate = 5−15ml.kg-1.h-1; High = 15−30ml.kg-1.h-1;
Very high = >30ml.kg-1.h-1
** Ethylene production at 20°C. Low = <0.1μl.kg-1.h-1; Moderate = 0.1−1.0μl.kg-1.h-1; High = >1.0μl.kg-1.h-1
*** Ethylene sensitivity. Low = not considered ethylene sensitive. Moderate = some damage may occur
with prolonged exposure. High = damaged significantly by short exposure / low levels of ethylene.
Note that respiration rate is highly variable and is strongly affected by variety and growing conditions.
