The anatomy of stems and leaves of two populations of the weed species Amaranthus retroflexus L. (red-root amaranth) (pop. AMARE1 having green stems covered in sparse hairs and AMARE2 with green but notably dense stem hairs) was analysed in order better to understand the uptake and translocation of herbicides that could be indicative of the species evolving resistance to herbicides. Samples of two populations (AMARE1 and AMARE2) were collected from arable land of the Maize Research Institute in Zemun Polje (Serbia) during 2006. Sampling was performed at the stage of full vegetative growth of plants. The results indicated high and very high significance of differences found in stem anatomy between two analysed populations, while leaf anatomy was not found to display significant differences other than in mesophyll thickness.
