C.  aTranscolation of C-glyphosate in johnsongrass (Sorghum halepense L. Pers.)as affected by growth stage and rhizome length  c1980  aStudies were conducted in the greenhouse on C-methyllabelled glyphosate translocation in johnsongrass as affected by rhizome length and growth stage.The amount of Cmesured by the liquid scintillation technique in the rhizome (2-8%)increased with rhizome length (10,20 or 30 cm)and tended to increase with growth stage (15-30 cm tall,45-60cm tall,or at seedhead),but the amount of C per g fresh rhizome weight was almost similar in all cases.1 aCOBLE, H.
