  I enjoyed your answer to this, and so many other of your responses.  I
am curious about item 4 - providing sucrose.  I read this somewhere and
put it in the botany book I wrote for the course I teach here.  When I
sent the book out for review, the reviewer jumped all over me, saying that
the sucrose would encourage the growth of bacteria.  We have ignored the
advice in our lab experiments, but we really haven't seen any differences
in those with sucrose and those with none.  Can you give any specific
advice on concentration?  Some have suggested putting aspirin with it to
prevent bacteria.  Sorry I'm not looking for this myself in the
horticulture journals, but the nearest library with horticulture journals
is at least 100 miles away (more likely 400) - or in some unknown person's
