Abstract

The biological activity of chemically synthesized nanocomposites (NCs) based on nanoparticles (NPs) of copper(I) oxide (NC Cu₂O/AG) and manganese hydroxide (NC Mn(OH)₂/AGs) based on an arabinogalactan (AG) natural polymer matrix is investigated for the development of a novel growth promoter for potato plants. Potato plants are grown on a nutrient medium, to which, instead of CuSO₄·4H₂O and MnSO₄·4H₂O salts, the corresponding NCs are added separately or in combination. It is found that NC Mn(OH)₂/AGs at a concentration of 0.0132%, both individually and in combination with NC Cu₂O/AG at a concentration of 0.0084%, stimulates incremental growth by 20% compared to the control in vitro potato plants. This NC enhances the growth of potato plants by elongation of the internodes and increases the biomass of the roots and aerial parts. The biomass of roots in plants, growing on a medium with two NCs, is 70% higher than in the control. Stimulation of the increase in biomass may be associated with the enhanced intensity of photosynthesis due to an increase in the amount of pigments in response to this NC. The content of carotenoids increases by 40% in response to the manganese-containing NC. Treatment with the studied NC reduces the amount of reactive oxygen species (ROS) in root tissues from 35 to 68% due to the enhanced activity of antioxidant enzymes. Catalase activity is boosted by 16 to 120% compared to the control. These data and previously obtained results suggest that the manganese NC shows considerable promise as a growth promoter in cultivated plants.

氢氧化锰和氧化铜纳米复合材料在阿拉伯半乳聚糖基质上离体培养马铃薯植株的生理生化参数

研究了以阿拉伯半乳聚糖(AG)为天然聚合物基质，化学合成氧化铜(NC Cu2O/AG)和氢氧化锰(NC Mn(OH)2/AGs)纳米复合材料的生物活性，为马铃薯植物生长促进剂的开发提供依据。马铃薯植株生长在营养培养基上，在营养培养基中分别或联合添加相应的nc，而不是CuSO4·4H2O和MnSO4·4H2O盐。结果表明，浓度为0.0132%的NC Mn(OH)2/AGs单独或与浓度为0.0084%的NC Cu2O/AG联合处理，可使马铃薯离体植株的生长比对照增加20%。该NC通过延长节间来促进马铃薯植株的生长，增加根系和地上部分的生物量。在含有两个NCs的培养基上生长的植物根系生物量比对照高70%。生物量增加的刺激可能与光合作用强度的增强有关，因为色素数量的增加是对这种NC的响应。类胡萝卜素含量对含锰NC的响应提高了40%。由于抗氧化酶活性的增强，NC处理使根组织中活性氧(ROS)的数量从35%减少到68%。过氧化氢酶活性比对照提高了16 - 120%。这些数据和先前获得的结果表明，锰NC作为栽培植物的生长促进剂具有相当大的前景。
