【 摘 要 】

Metal nanoparticles have unique properties that increase the growth and development of seeds of both crops and trees, thereby increasing plant productivity. The treatment of seeds with metal nanoparticles may ensure getting a high quality planting material from seeds with its further preservation. The possibility of using suspensions of nanoparticles of iron and copper in the range of concentrations from 2•10-4 to 2•10-2 % when preparing the planting material in nurseries and in the conditions of the forest zone on various soils is shown. It has been revealed that germination of seeds in iron and copper nanoparticles (30-60 nm) suspensions with metal concentration of 2•10-3% results to the increase of the plant's resistance to infectious lodging (by 1.9 times), the survival rate (by 40-60%), and it's annual height (by 15%) compared to control. Although the use of nanoparticles in germination promotes the peroxidase activity, it inhibits catalase activity by showing the plant resistance to stress, while increasing growth processes. Seed germination increases to 10 % above the control, whereas the root growth increases by 25-30 %.
