Translocation of Streptomycin from Coleus Leaves and Its Effect on Rhizosphere Bacteria.
Autoradiographs showed that when streptomycin is applied to leaves of coleus plants (1000 to 3600 micrograms per plant) the antibiotic or some by-product is translocated laterally and downward. The translocated material does not alter rhizosphere microorganisms quantitatively. Gram-negative rhizosphere bacteria, however , are suppressed through the 8th day after treatment.
