Hi List & Jan,
I was thinking more of the lower temperatures highlanders
get in their mountian homes. Not really of the danger from frost.
What are the reasons highland Neps don't do as well in warmer temps,
and visa versa for the lowlanders? I'm assuming some of their
proteins (enzymes) don't work at certain temperatures due to slight
modifications that don't change the use of a protein, just the
temp it works at. If this is so, then hybrids between high and low
land Neps should give rise to plants that are equally adapted to
both sorts of temperature ranges, since they'll get working copies
of both... Has anyone noticed if this is true or not?
