Abstract
The effects of 5 hormone-type herbicides were studied on staminal hair cells of Tradescantia, stipular cells of Vicia faba, petal cells of Allium cepa and A. fistulosum, root tip cells of Triticum vulgare, and pollen grains of Trades cantia. The herbicides were 2,4-D; 2,4,5-T; 5-D, MCP, and SES, applied in 10 different concentrations. The chemicals induced many abnormalities during mitosis, such as chromosome bridges due to stickiness, retardation of chromosome movement at anaphase; binucleate cells, multinucleate cells with multisepta, formation of incomplete cell walls, and retarded differentiation of meristematic tissues. These effects upon mitosis were directly related to the malformations produced in mature plants.
