The influence of nanocomposites (NC) of selenium in matrices of arabinogalactan (Se/AG) and starch (Se/St) on in vitro vegetation of potato plants, peroxidase activity, and reactive oxygen species has been thoroughly studied. It has been shown that these nanocomposites of selenium have antimicrobial effect to the phytopathogenic bacterium Clavibacter michiganensis ssp. sepedonicus (Cms). In the present investigation, it has been shown that Se/AG NC (6.4% of Se) and Se/St NC (12.0% of Se) have no negative impact on the potato plants healthy and Cms infected, while stimulating their growth, number of leaves and weight of the vegetative part. Se/AG NC has shown a positive effect on potato plants by increasing its immune status by increasing the ROS content and increasing the peroxidase activity. With the use of the element analysis technique, it has been shown that scrutinized nanocomposites are not accumulated in potato plants after the bactericidal processing with the nanocomposites. Se/AG NC and Se/St NC as potential agents used for treatment of potato plants against pathogenic bacteria.

具有多糖基质的硒纳米复合材料可刺激被环腐病原菌感染的马铃薯植株体外生长。

阿拉伯半乳聚糖（Se / AG）和淀粉（Se / St）基质中硒的纳米复合物（NC）对马铃薯植物体外植被，过氧化物酶活性和活性氧种类的影响已得到详尽研究。已经表明，这些硒的纳米复合物对植物致病性细菌密歇根州立克氏杆菌属具有抗菌作用。sepedonicus（Cms）。在本研究中，已表明Se / AG NC（硒的6.4％）和Se / St NC（硒的12.0％）对健康和受感染的Cms马铃薯植物没有负面影响，同时刺激了它们的生长，数量叶子和营养部分的重量。Se / AG NC通过增加ROS含量和增加过氧化物酶活性来提高其免疫状态，从而对马铃薯植物显示出积极的作用。通过使用元素分析技术，已经显示，在用纳米复合物杀菌处理之后，经仔细检查的纳米复合物并未积聚在马铃薯植物中。Se / AG NC和Se / St NC是潜在的药剂，可用于处理马铃薯植物中的致病细菌。
