Move a tree to the opposite hemisphere: What would happen with it six months out of phase?

[Charles]

What would happen if you took a deciduous tree, say in September when we enter fall in the northern hemisphere and relocated it to the southern hemisphere?

In the fall, that tree in the US, is beginning to shed leaves and it is in its summer -> fall -> winter cycle. What would happen if you carefully and swiftly relocated it to Peru or Chili or some other South American country where trees were transitioning from winter to spring? The tree would be six months out of phase. As the tree itself was transitioning to fall/winter, the environment is transitioning to summer.

What the tree do?

I'm pretty sure it would revert to behave according to its new environment. As the days got longer, it would go into growth mode again - new leaves would bud. The old ones would die off but probably more slowly than they do in fall. Then when the southern hemisphere fall arrived, it would shed.

Eventually...but what about the first year? Also, how long would it take to get "in phase" with its new environment? Would it simply "skip" a cycle of shedding or growing leaves?

we have this kind of thing happen with fruit trees here, they get very "confused"some years with our odd seasons, as we don't have the strong winters and mild mid seasons that they have developed for, this year our peaches were simultaniously green and overripe on the tree, they all went off within 2 days of picking and I got no preserves done of course these are trees that have been here all their lives, so slightly different situation.
