The article presents the results of studying the effect of Cu and Fe nanoparticles on the development of Scots pine seedlings of two genotypically different populations growing in different geobotanical, soil-geological conditions in Orenburg oblast. It was found that the morphobiological reaction of seedlings to the effect of Cu and Fe nanoparticles, regardless of the origin of the seed material, is unidirectional in seedlings obtained from pines adapted to an increased natural geochemical background for Cu and Fe (population of the Kvarkensky district), and in seedlings obtained from seeds collected from pine trees growing in a lower geochemical background conditions (population of Buzuluk region). The presence of Cu nanoparticles had a toxic effect on the growth of pine seedlings while Fe had a stimulating one. However, the morphometric parameters of the seedlings obtained from the seeds collected in the population of the Kvarkensky district significantly differed from the seedlings of the Buzuluk district. In the presence of Cu nanoparticles in the medium, the first group of seedlings exceeded the second in main root length by 2.1–4.9%; in the number of adventitious roots, by up to 10.2%; and in the length of adventitious roots, by 0.84–7.61%. In the presence of Fe nanoforms in the medium, the first group of seedlings also exceeded the second in main root length by 0.39–2.23%; in the number of adventitious roots, by up to 3.1%; and in the length of adventitious roots, by 0.55–1.04%.

本文介绍了铜和铁纳米颗粒对生长在奥伦堡州不同植物学、土壤地质条件下的两个基因型不同种群的苏格兰松幼苗发育影响的研究结果。发现幼苗对 Cu 和 Fe 纳米粒子的影响的形态生物学反应，无论种子材料的来源如何，在从松树获得的幼苗中都是单向的，这些幼苗适应了增加的 Cu 和 Fe 自然地球化学背景（Kvarkensky区），以及从生长在较低地球化学背景条件下的松树（Buzuluk 地区的种群）收集的种子中获得的幼苗。Cu纳米颗粒的存在对松树幼苗的生长具有毒性作用，而Fe具有刺激作用。然而，从 Kvarkensky 区种群中收集的种子获得的幼苗的形态参数与 Buzuluk 区的幼苗显着不同。在培养基中存在Cu纳米颗粒的情况下，第一组幼苗的主根长度超过第二组2.1-4.9%；在不定根数量上，高达10.2%；不定根长度增加 0.84-7.61%。在培养基中存在Fe纳米形态的情况下，第一组幼苗的主根长度也超过第二组0.39-2.23%；在不定根的数量上，高达3.1%；不定根长度增加 0.55-1.04%。在培养基中存在Cu纳米颗粒时，第一组幼苗的主根长度超过第二组2.1-4.9%；在不定根数量上，高达10.2%；不定根长度增加 0.84-7.61%。在培养基中存在Fe纳米形态的情况下，第一组幼苗的主根长度也超过第二组0.39-2.23%；在不定根的数量上，高达3.1%；不定根长度增加 0.55-1.04%。在培养基中存在Cu纳米颗粒时，第一组幼苗的主根长度超过第二组2.1-4.9%；在不定根数量上，高达10.2%；不定根长度增加 0.84-7.61%。在培养基中存在Fe纳米形态的情况下，第一组幼苗的主根长度也超过第二组0.39-2.23%；在不定根的数量上，高达3.1%；不定根长度增加 0.55-1.04%。在不定根的数量上，高达3.1%；不定根长度增加 0.55-1.04%。在不定根的数量上，高达3.1%；不定根长度增加 0.55-1.04%。
