I found an interesting experiment by Eduard A. Strasburger (1893) referenced
in Salisbury & Ross, where he sawed off 20 m tall trees and placed them in
buckets of copper sulfate, picric acid and other poisons. As these poisonous
fluids ascended up the tree, they killed the tissue. Transpiration only
stopped when the leaves died. He also did similar experiments by scalding
Wisteria vine.
