| ABSTRACT: The monitoring of phytochemicals with potentially toxic properties can be assessed by observing the physiological and cellular alterations of the test organism exposed. This present study aimed to evaluate the cytotoxic and genotoxic potential of aqueous extracts of leaves and roots of Macroptilium lathyroides weed on the cell cycle of lettuce. Bioassays were conducted in a germinator (25 oC) with aqueous extract at concentrations of 0, 5, 10, 20 and 40% p v-1, obtained from fresh leaves and roots. For biological, lettuce root meristems were used for the preparation of slides using the technique of squashing. All blades were observed with an optical microscope at a magnitude of 400x. A total of 5,000 cells were analyzed for each treatment, and... |
