Extract
The question of direction and rate of movement of herbicidal chemicals in aquatic plants often arises in considering effective methods of chemical control for plants of this type. Results obtained from studies of solute movement within terrestrial plants are not directly applicable to totally submersed aquatic species for two reasons: a) A liquid medium, in which dissolved substances may be distributed uniformly, surrounds all parts of the aquatic plant, and b) Vascularization is minimal in leaf and stem tissues of submersed aquatics. Reports of experiments yielding quantitative data on translocation patterns in submersed aquatic plants are rare or nonexistent. It is probable that mechanical difficulties encountered in separating root systems from leaf or stem tissues of submersed plants have been of greater hindrance to translocation experiments with aquatic species than any other factors.
