The aim of presented study was to test nutritional properties of potato tubers and silver ions accumulation pattern after foliar application of silver nanoparticles (AgNPs) during potato vegetation. Potato plants were sprayed with different concentration of Ag nanoparticles (0.1, 1.0 and 10 mg·dm) synthesized with incorporation with sodium dodecyl sulphate (SDS) and sodium citrate as stabilizing agent. The lowest amounts of silver ions were transported to the tubers after spraying with AgNPs synthesized with SDS, rather than with citrate. Nevertheless silver ions accumulation in tubers was negligible. SDS method of synthesis was more favourable in terms of nutritional properties of potato tubers. The highest tested concentration of AgNPs_SDS had a favourable effect on a variety of macro- and micronutrients, ascorbic acid and soluble sugars. In turn, lower concentrations of AgNPs_SDS increased the content of phenolic compounds and free radical scavenging efficiency of tubers. These correlations were also confirmed by Principal Component Analysis.
本研究旨在测试马铃薯块茎的营养特性和叶面喷施银纳米粒子（AgNPs）后银离子的积累模式。马铃薯植株用不同浓度的 Ag 纳米粒子（0.1、1.0 和 10mg·dm）进行喷洒，这些 Ag 纳米粒子是通过将十二烷基硫酸钠（SDS）和柠檬酸钠作为稳定剂来合成的。用 SDS 合成的 AgNPs 喷洒后，向块茎中输送的银离子量最少，而用柠檬酸钠合成的则不然。然而，在块茎中积累的银离子可以忽略不计。SDS 法的合成在马铃薯块茎的营养特性方面更具优势。测试的最高浓度的 AgNPs_SDS 对各种大量和微量营养素、抗坏血酸和可溶性糖有积极影响。相反，较低浓度的 AgNPs_SDS 增加了块茎中酚类化合物的含量和自由基清除效率。这些相关性也通过主成分分析得到了证实。
