Re: Weaver - early prairie research

Hi.

I have a related question. I'm looking for a list of research papers describing allelopathy -- 
the chemical process 
that plants use to keep other plants from growing too close to them -- displayed by native 
midwestern plants. My 
literature searches have not been successful. It seems this would be very useful information 
for confronting weed 
problems. For exmaple... I'm planning on planting a few black walnuts. All other factors 
being equal, would it be 
useful to plant them near the crown vetch I'd like to eradicate? Does jugulone (spelling?) 
inhibit crown vetch 
growth?

Can anyone direct me to a resource about allelopathy displayed by native plants... and weeds 
for that matter?

THANKS!!
