The paper presents a study of the effect of chemically synthesized selenium nanocomposites (Se NCs) in natural polymer matrices arabinogalactan (AG) and starch (ST) on the viability of the potato ring rot pathogen (), potato plants in vitro, and the soil bacterium . It was found that the studied Se NCs have an antibacterial effect against the phytopathogenic , reducing its growth rate and ability to form biofilms. It was revealed that Se NC based on AG (Se/AG NC) stimulated the growth and development of potato plants in vitro as well as their root formation. At the same time, Se did not accumulate in potato tissues after the treatment of plants with Se NCs. The safety of the Se NCs was also confirmed by the absence of a negative effect on the growth and biofilm formation of the soil bacterium . The obtained results indicate that Se NCs are promising environmentally safe agents for the protection and recovery of cultivated plants from phytopathogenic bacteria.
本文研究了化学合成的硒纳米复合材料(Se NCs)在天然聚合物基质阿拉伯半乳聚糖(AG)和淀粉(ST)中对马铃薯环腐病菌()、马铃薯离体植株和土壤细菌的影响。研究发现,所研究的 Se NCs 对植物病原菌具有抗菌作用,降低了其生长速度和生物膜形成能力。结果表明,基于 AG 的 Se NC(Se/AG NC)刺激了马铃薯离体植株的生长和发育,以及其根系的形成。同时,用 Se NC 处理植物后,Se 并未在马铃薯组织中积累。土壤细菌的生长和生物膜形成也没有受到 Se NCs 的负面影响,证实了 Se NCs 的安全性。研究结果表明,Se NCs 是一种有前途的环境安全剂,可用于保护和恢复农作物免受植物病原菌的侵害。
