Can indoor-grown trees form tree rings without experiencing a winter season?

[g33kski11z]

Sorry if this is the wrong section but this question comes from a convo I had with some friends the other night..

Say you were able to grow a full size tree indoors (assuming you had the space, nessesary lighting, soil, etc..) and kept it under 18 hours of light and 6 hours of dark indefinitly. Would it still create tree rings? Would it loose its leaves? What is the mechanisms for these?

thanks for any insight provided..

Nothing... :-( not going to lie, I'm kinda disappointed..

If it didn't have a 'winter' then most species would just grow continually.

For instance most tropical species don't form tree rings because they don't experience a summer growing season followed by a winter with no new growth.
