title: [Investigations on the effects of a carbamate herbicide and of colchicine on mitosis of Allium cepa and Hordeum vulgare].
abstract: The marked differences in sensitivity of mitotically active root tip cells of Hordeum and Allium observed in response to a carbamate herbicide are not found in response to treatment with the spindle poison colchicine. Hordeum was less sensitive than Allium. Colchicine inhibited the spindle and caused c-mitoses and polyploidy. The carbamate herbicide inhibited the spindle and strongly affected the chromosomes; arrest of mitosis was primarily caused by stickiness and pycnosis of the chromosomes, spindle inhibition was of secondary importance.
