Growth effects, uptake and metabolism of trifluralin in tissue cultures

Growth effects, uptake and metabolism of trifluralin (alpha, alpha, alpha-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine) in carrot (Daucus carota L.) and tobacco (Nicotiana tabaccum L.) callus tissue were determined. Carrot callus was initiated from tap root tissue on Murashige and Skoog medium with kinetin and 2,4-dichlorophenoxy acetic acid (2,4-D). Tobacco callus was initiated from pith tissue on Murashige and Skoog medium with indole-3-acetic acid (IAA) and kinetin.
