Abstract
Sodium dimethyldithiocarbamate, applied to the roots of tomato and bean plants, markedly decreases the rate of transpiration and prevents stomatal opening. The chemical also causes a large reduction in water movement associated with metabolic root pressure. The concentration of total amino acids moving out of the root system is reduced by as much as 50% of normal. Transpiration and stomatal opening of detached leaves from untreated plants are not affected appreciably by solutions of sodium dimethyldithiocarbamate.
