【 摘 要 】

The significant reduction of shrubs and grass plants biodiversity between urban and reserved territory could be a biomarker of human impact and effect of urbanisation. We could conclude that trees are more resistant to climate change and anthropogenic pressure.The research of cytogenetic parameters for English oak seed progeny in the areas with different levels of anthropogenic pollution was carried out. High level of mitotic pathologies and mitotic activities of seed progeny plantlets from trees growing near freeway was observed. Also high level of variability indices, such as percentage of prophase cells, metaphase cells, mitotic pathologies were seen.
