http://www.bulbs.com/ has several citations that relate to this question.
Use the search engine and enter "ethylene gas and its effects" to locate
the articles.
The amounts of ethylene gas that will trigger a response can be as low
as 10 parts per million to trigger the ripening process of kiwifruit
stored at 33 degrees F.
It is important to know the source of the ethylene - Apples are a high
producer of ethylene - the temperature, and the minimum length of
exposure the target produce or bulb has to the gas.
This site is a profession organization of Dutch growers and should be
reliable.

According to information I received from a researcher in Holland, the amount
of ethylene gas given off by fruit such as apples is relatively small
Judy:
Did your researcher provide any hard figures? I have seen claims of apples
producing anywhere from 30 to 200 ppm when stored in the fruit or vegetable
crisper of a home refrigerator. Variables might include "ripeness" of the apple,
variety, temperature and ventilation.
