L.S.

I am a new subscriber to the forest list, out of disciplinairy
interest as well as curiosity. On this very first occasion I
am addressing you all with a question that may intrique some and bore
others. Nonetheless I would appreciate any feedback to my address:

with gratitude and pleasure.

Question: We are growing waterhyacinth in a 2 reservoirs, geographically
only 30 miles apart. In reservoir 1 the plants grow profusely. In the
other, number 2, inoculated with plants from the same source, growth is
slow and retarded. The latter is bordered(4-5 meters from the reservoir
edge)by fully grown Eucalyptus trees, shedding leafs and seeds into the
water.

Does anyone have any information on Eucalyptus seeds or leaves having
growth inhibiting properties.

Could it be that roots from the trees that enter the reservoir disperse
root-exhudates into the water that may cause the waterplants to develop
very slowly or hardly at all?

Anyone has any such experience or possible other solutions?
