Ethylene
Captions available
The idea
Ethylene, a volatile gas, triggers fruit ripening, leaf and flower abscission, and senescence, released more from aging or wounded tissue.
In practice
Storing unripe avocados in a sealed bag traps the ethylene one ripening fruit releases, speeding up ripening in the rest.
Where people slip
Ethylene's effect on nearby fruit works because it is a gas — sealing fruit away from ventilation concentrates rather than dilutes it.
