Abstract
Trifluralin was found to induce isodiametric enlargement ofAllium cepa root tip cells in the elongation zone. It enhanced the endogenous oxygen uptake of the excised root tips. The herbicide was found to have no marked effect on the dry weight of the root tips. It is suggested that the herbicide may exert its effect onAllium cepa root tips through its enhancement of ethylene production.
