Long-term dynamic of cytogenetic parameters of the seedlings apical root meristem was analyzed for the Quercus robur for Central Black-Soil region. Central Black-Soil region located in the European part of Russia (geographical coordinates for Voronezh city: 51.660781; 39.200269) in the temperate climate zone. Annual climate indicators were analyzed to determine the possible influence of precipitation amount and temperature fluctuations during pollination and seed formation in the parent trees. Seed progeny cytogenetic parameters of trees growing in urban and suburban conditions were characterized by an increase in mitotic activity and the proportion of cells with mitotic pathologies, the appearance of micronucleus and residual nucleoli in mitosis. There was possible consequence of the complex technosphere negative factors impact on populations. The mitotic index for urban populations (from 6.8% to 9.5 %) was approximately at the same level for all years in long-term dynamics. There was a sharp decrease in mitotic activity (4.6 %) for the control area in 2019 compared with the data for 2008 (10.5%). The proportion of cells with mitosis pathologies in the meristems of urban seedlings was increased. There was a significant prophase-cells proportion increase among the seedlings. The reduction of number of pathologies may indicate the check-point repair system operation.

夏栎幼苗顶端根分生组织细胞遗传学参数的长期动态分析为中央黑土地区。中部黑土区位于俄罗斯欧洲部分（沃罗涅日市的地理坐标：51.660781；39.200269），位于温带气候区。分析年度气候指标以确定在亲本树授粉和种子形成过程中降水量和温度波动的可能影响。在城市和郊区条件下生长的树木的种子后代细胞遗传学参数的特征是有丝分裂活性增加，有丝分裂病理的细胞比例增加，有丝分裂中出现微核和残留核仁。复杂的技术圈负面因素对人口的影响可能产生后果。城市人口的有丝分裂指数（从 6.8% 到 9. 5 %) 在长期动态中的所有年份大致处于相同水平。与 2008 年的数据（10.5%）相比，2019 年对照区的有丝分裂活性（4.6%）急剧下降。城市苗木分生组织中出现有丝分裂病变的细胞比例增加。幼苗中前期细胞比例显着增加。病理数量的减少可能表明检查点修复系统运行。
