Translocation and Persistence of Cycloheximide and Oligomycin In Northern Pin Oaks
Abstract:The antibiotics cycloheximide and oligomycin moved systemically in Quercus ellipsoidalis E. J. Hill. They were absorbed by seedling roots from drenched soil, by foliage sprayed with water solutions, and by trunks cone-injected through chisel cuts. Following trunk injections, these antibiotics were translocated both upward and downward in the sapwood. Cycloheximide was absorbed and translocated faster, further, and in greater quantities than was oligomycin. Cycloheximide accumulated in the leaves while most of the oligomycin remained in the trunk tissues especially near the point of injection. Detectable amounts of the antibiotics disappeared rapidly from the oak tissues.
