The hunt for allelopathic plants

I remember doing a lab in Plant Ecology at where we tested the effects of
leaf  rinses and leaf extracts on the germination of Jack pine seeds (pinus
banksiana).  We collected jack pine cones, placed them in an oven at low
heat to get them to open (they are serotinous cones), and shook out the
seeds.  We placed the seeds on a layer of washed beach sand in sterile petri
dishes.  Then we moisted the seeds with a number of different solutions.  We
homogenized the leaves of wild black cherry (Prunus serotin), reindeer moss,
and jack pine.  We aslo placed the leaves of these 3 plants in large plastic
funnels and sprayed water over them to mimic the effect of rain washing
chemicals off the leaves.  As I remember it worked quite well. Our
instructor had an article on this, which I believe was from Ecology. You
might try a an online literature search.
Good Luck, Judy Kelly, Biology Dept.  Henry Ford college
