Abstract

To meet the growing demand for food it is necessary to develop new approaches to pre-sowing seed treatment, including with modern nanotechnology. The paper presents data on the effect of the pre-sowing treatment of rice seeds with nanoparticles of individual trace elements and their compositions. It is found that the pre-sowing treatment of rice seeds with 10^–7% of Fe NPs and compositions (B 10^–5%, Mo 10^–7%, Mn 10^–6%, Fe 10^–7% NP mixtures) increased the seed germination energy and seed germination by 9.4 and 11.8%, respectively, compared with the control. Fe 10^–7% NPs contribute to a three-fold increase in seedling root length and a 110.9% increase in the seed/seedling viability index as compared to the control. The quantitative anatomical parameters of the leaves of rice seedlings show an increase in the area of water-storage tissue by 72.2%, chlorophyll-containing tissue by 22.9%, area of vascular bundles by 66.5%, leaf thickness by 21.9% for the case of the pre-sowing treatment of seeds with nanopreparations with a micronutrient-NP composition compared to the control.

为满足日益增长的粮食需求，有必要开发新的播种前种子处理方法，包括利用现代纳米技术。本文介绍了用各种微量元素纳米粒子及其成分对水稻种子进行播前处理的效果。研究发现，与对照组相比，用 10-7% 的 Fe NPs 及其组合物（B 10-5%、Mo 10-7%、Mn 10-6%、Fe 10-7% NP 混合物）对水稻种子进行播前处理后，种子发芽能和种子发芽率分别提高了 9.4% 和 11.8%。与对照相比，Fe 10-7% NPs 使幼苗根长增加了三倍，种子/幼苗活力指数增加了 110.9%。水稻秧苗叶片的定量解剖参数显示，与对照组相比，播种前用含有微量营养元素-NP成分的纳米制剂处理种子，储水组织面积增加了 72.2%，含叶绿素组织增加了 22.9%，维管束面积增加了 66.5%，叶片厚度增加了 21.9%。
