Trong nghiên cứu này, hạt nano cobalt (nCo) các liều lượng khác nhau đã được sử dụng để xử lý hạt đậu tương (Glycine max L.) giống ĐT12. Các chỉ tiêu vi sinh trưng, phát triển, năng suất của cây, hàm lượng các thành phần dinh dưỡng của hạt được theo dõi và đánh giá trong suốt một vụ. | Đánh giá ảnh hưởng của việc xử lý hạt đậu tương bằng nano cobalt trước khi gieo lên sự sinh trưởng, phát triển, năng suất và chất lượng của giống đậu tương ĐT12 TAP CHI SINH HOC 2019, 41(2): 61–70 DOI: EFFECTS OF SEEDS TREATED WITH COBALT NANOPARTICLES ON GERMINATION, GROWTH, YIELD AND QUALITY OF SOYBEAN CULTIVAR DT12 Le Thi Thu Hien1,2,*, Tran Thi Truong3 1 Institute of Genome Research, VAST, Vietnam 2 Graduate University of Science and Technology, Vietnam 3 Field Crops Research Institute, Vietnam Academy of Agriculture Science, Vietnam Received 1 April 2019, accepted 25 May 2019 ABSTRACT Seed treatment using metallic nanoparticles to stimulate germination and improve crop yields has been published and widely applied in agriculture production. To assess the safety of such methods on plants, the effectiveness and safety of the treatment of soybean Glycine max L. DT12 seeds with cobalt nanoparticles (nCo) before sowing were investigated. Seeds of soybean cultivar DT12 were treated with nCo at two different concentrations ( and mg/kg seed) before sowing. Germination rate, growth speed, soybean yield and bean nutrient components were examined throughout a season. Results implied that at a concentration of mg/kg, nCo significantly increased germination rates, plant heights, total pods per plant, number of pods having 3 seeds, and crop productivity compared to both the control and seeds treated with a highter concentration of mg per kg of seed. However, no significant differences were found between treatments in terms of growth level and seed nutrient contents, including moisture, ash content, mineral (K, Mg and Fe) and crude protein components. In seeds treated with higher concentration, the Ca content was dramatically lower than that of the control and seeds treated with a low concentration, but bean quality was not affected. This study .
