Summary. High concentrations of 2,4-D and picloram interfered with the downward movement of 14c-assimilates infield-grown vines. The interference in translocation was appreciably greater with picloram than it was with 2,4-D, Although basipetal translocation was retarded, translocation within the treated shoots continued from the vegetative part to the clusters. Translocation of 2,4-D appeared to follow the same route as 14c-assimilatcs for the most part. Formative effects were absent on untreated grape shoots although the adjacent shoots treated with 2,4-D or picloram on the same cordons were killed; however, formative effects were evident on some of the stump sprouts which developed after the vines were harvested. The malformed leaves on the stump sprouts were twelve or more nodes from the base of the shoots, while 14c was in the more basal leaves.Thompson Seedless (Sultanina) rootings treated with 20 000 ppm 2,4-D or picloram transported less 14C to the roots than did the controls. Treatment with either herbicide resulted in a marked increase in the labelling of the stems.Effet du 2,4-D et du pichlorame sur la migration de métabolites marqués au 14C dans Vitis vinifera L.
