This study is aimed to explore the capacity of metal nanoparticles (NPs) iron, zinc, copper and their combinations introduced in the Murashige-Skoog (MS) nutrient medium (NM) to affect the growth and development of tomato plants (Solanum lycopersicum L.). NPs were prepared by a flow-levitation method. Metal NPs were characterised by transmission and scanning electron microscopy, X-ray phase analysis. Average NPs diameters were: iron - 27.0 nm, zinc - 54.0 nm, copper - 79.0 nm. MS NM was modified by substitution of common metal sulphates by neutral metal NPs instead of salts. Tomato seedlings cultivation on NM MS with NPs instead of salts assures improved seedling parameters (root length and root activity) in comparison with plants grown on standard MS. Venice cultivar tomato seedlings grown on NM with metal NPs demonstrated an increase in: seed germination by 10-180%, root length by 10-20%, and root activity by 10 -125%. After 45 days of cultivation, tomato seedlings were transplanted in a greenhouse and were grown up to the harvest. Effects in seed germination and increase of crop mass depended on metal nature and NPs concentration.

番茄对营养培养基中引入金属纳米颗粒的反应。


本研究旨在探讨 Murashige-Skoog (MS) 营养培养基 (NM) 中引入的金属纳米颗粒 (NPs) 铁、锌、铜及其组合对番茄植株 (Solanum lycopersicum L. ）。纳米颗粒通过流动悬浮法制备。通过透射电子显微镜、扫描电子显微镜、X 射线物相分析对金属纳米粒子进行了表征。平均纳米粒子直径为：铁 - 27.0 nm，锌 - 54.0 nm，铜 - 79.0 nm。 MS NM 是通过用中性金属纳米颗粒代替盐来取代普通金属硫酸盐来进行修饰的。与在标准 MS 上生长的植物相比，在 NM MS 上用 NP 代替盐培养番茄幼苗可确保改善幼苗参数（根长和根活性）。在含有金属纳米粒子的 NM 上生长的威尼斯品种番茄幼苗表现出以下方面的增加：种子发芽率增加 10-180%，根长增加 10-20%，根系活性增加 10 -125%。培育45天后，番茄幼苗被移植到温室中并长大直至收获。对种子发芽和作物质量增加的影响取决于金属性质和纳米颗粒浓度。
