...probably the only greenhouse where weeds and orchids grow side by side, and where people pay more attention to weeds. It's certainly one of the few greenhouses where plants wear bandages. Professor Kenneth V. Thimann put them on after injecting hormones into the stems to see how growth was affected. His investigation of plant galls may lead to new information on animal cancers...
...discovery was made by Kenneth V. Thimann, Professor of plant physiology, after months of experimentation at the Atkins Institute in Soledad, Cienfuegos, Cuba. The weed apparently eliminated by the experiment is the Aroma marabu weed, which had overgrown large acreages of sugar land on the island and is also a problem to cattle raisers in the region...
Outlining his work in the current issue of Science, the magazine of the American Association for the Advancement of Science, Thimann said, "the experiments are being continued, as they give promise of the possible reclamation of land which up to now was considered virtually unavailable...

...recent experiment was to put a "growth inhibitor" (iodoacetic acid) in the water. It did not kill the cells, but stopped their growth by breaking a necessary chain of chemical reactions. Then, one after another, Thimann added likely compounds, hoping to see growth start again. He found that malic acid (which is found in apples) would overbalance the evil influence of iodoacetic acid, allowing the cells to grow. This proved that malic acid was somehow involved in the chain of reactions which the inhibitor had broken...
