THE CYTOLOGICAL EFFECTS OF THE HERBICIDES TERBUTRYNE AND PROMETRYNE AND THE INSECTICIDE TRIAZOPHOS ON VICIA FABA

The effects of the twe triazine herbicides terbutryne and prometryne and the organophosphorous insecticide triazophos, on early root growth, mitosis and chromosomes in root meristems of V.faba have been studied .Roots were treated with different concentraThe used pesticides, resulted in the retardation of early seedling root growth. This was generally associated with a reductionb of mitotic activity in root meristems. The degree of mitotic inhibition was generally dose dependent. MI values were decreased
