Graphical abstract: Summary of experiments relating to the effects of nanoscale zerovalent cobalt on growth and photosynthetic parameters of soybean Glycine max (L.) Merr. DT26 at different stages. In this study, the nanoscale zerovalent cobalt (NZVC) made from Vietnam and USA with different concentrations (0, 0.17 and 16.7 mg/kg seed) were used for treatment soybean seeds. The effect of NZVC on the growth, photosynthetic parameters expressed by Fo (initial fluorescence), Fm (maximal fluorescence), Fv/Fm (maximal photochemical efficiency), ΦPSII (effective quantum yield of photosystem II), ETR (photosynthetic electron transport rate), Pn (net photosynthetic rate) and content of chlorophyll a and b at different stages (V1, V3, V5 and R1) in soybean leaves were investigated. The results have shown that the NZVC treated soybean’s growth indices, photosynthetic parameters, and chlorophyll a and b content were increased obviously compared with that of the control. These values reach maximum at fifth (V5) trifoliate stage, whereas they were significantly decreased at begin at flowering (R1) stage. The real productivity of the experimental formulas exceeded the control (5%), while the quality of grain was significant different among the plots. (TIF 824 kb)
