Coppe and zinc are priority pollutants in city soils. Copper and zinc are the limiting factors for lawn grasses. Cell selection can increase the resistance of lawn grasses to zinc and copper. The effect of zinc on the morphogenic ability of the callus was determined. The results of this study showed that zinc is less toxic to calli than copper. The method of obtaining lawn grass resistant to zinc has been developed. The results were used to develop the cell selection technology for obtaining plants resistant to the complex effect of zinc and copper. Concentrations of Copper (75 mg/l) and zinc (150 mg/L) were selected as selective. The author developed the cell selection scheme for obtaining plants resistant to the complex effect of Cu and Zn. The regenerants showed increased resistance to copper and zinc.
铜和锌是城市土壤中的优先污染物。铜和锌是草坪草的限制因素。细胞选择可以提高草坪草对锌和铜的抗性。研究了锌对愈伤组织形态发生能力的影响。研究结果表明，锌对愈伤组织的毒性小于铜。已经开发出了抗锌的草坪草的获取方法。这些结果用于开发用于获得对锌和铜的复杂作用具有抗性的植物的细胞选择技术。选择铜（75mg/L）和锌（150mg/L）的浓度作为选择性。作者开发了用于获得对 Cu 和 Zn 复合作用具有抗性的植物的细胞选择方案。再生植株表现出对铜和锌的抗性增强。
