Abstract

Advanced nanotechnologies allow synthesizing nanoparticles (NPs) with the given physical and chemical properties providing an opportunity to study the effects and mechanisms of the influence of NPs on plants in order to improve their productivity. In this study, Zn NPs introduced in the polymer coating are used as a preparation for the presowing treatment of pepper seeds. It is found that Zn NPs in concentrations of 10^–5 and 10^–6% in the composition of polymers accelerated plant growth and led to a significant increase in the number of leaves and buds, while the root mass volume increased on average by 10–30% compared to the control plants. After seed treatment with Zn NPs with a concentration of 10^–6%, the proline content in plant leaves increases by 58% (p ≤ 0.05); and the protein content, by 20% (p ≤ 0.05). The treatment of seeds with Zn NPs at a concentration of 10^–5% leads to the sugar content increasing by 36% (p ≤ 0.05), and the chlorophyll content, by 52% (p ≤ 0.05) compared with the control.

用纳米锌颗粒对辣椒种子进行播前处理后对其形态生理参数的改善

摘要先进的纳米技术可以合成具有特定物理和化学特性的纳米粒子（NPs），这为研究 NPs 对植物的影响效果和机制提供了机会，从而提高植物的产量。在这项研究中，将 Zn NPs 引入聚合物涂层中，作为辣椒种子播前处理的制剂。研究发现，在聚合物成分中浓度为 10-5% 和 10-6% 的 Zn NPs 可加速植物生长，并显著增加叶片和芽的数量，而与对照植物相比，根的体积平均增加了 10-30%。用浓度为 10-6% 的 Zn NPs 处理种子后，植物叶片中的脯氨酸含量增加了 58%（p ≤ 0.05）；蛋白质含量增加了 20%（p ≤ 0.05）。用浓度为 10-5% 的 Zn NPs 处理种子，与对照相比，糖含量增加了 36% (p ≤ 0.05)，叶绿素含量增加了 52% (p ≤ 0.05)。
