Managing etrhylene gas in storage (apples) query

marknmtOctober 23, 2013

Wish I knew more about this aspect of storing apples and would appreciate any comments, links to reading, and the like. Right now I'm assuming that it would be wise to open the unvented polyethylene bags from time to time, but have no idea of what's reasonable. Perhaps it'd be better to use perforated bags?



Oooop .... I typoed "ethylene" in the subject line and apparently can't edit it.

Are you concerned only about the apples or other things like cuttings you might have in the same fridge? I haven't worried about the former but have about the later.

You want some ventilation but not so much that the apples shrivel.

Only the apples- I'll get some cuttings later, but I hadn't thought of the ramifications for them! Guess I should.

Ethylene is deadly to cuttings and nursery stock. So don't store much fruit with that material.

Thank you. Aside from apples what else gives off ethylene?

This could present a problem for me when I'm storing cuttings in late winter/early spring. I've got apples everywhere right now.

Good problem to have.

In my experience, a freezer full of Goldrush apples (kept at 38F through the winter by a thermostat) did not experience any problem. Apples were in good shape in May. Somehow ethylene does not affect the apples themselves.

When I chilled tulip bulbs, apples and onions were the ones I kept out of the refrigerator.
