[Effects of applying selenium on selenium allocation, grain yield, and grain quality of two maize cultivars].

A pot experiment with conventional maize cultivar ZD958 and glutinous maize cultivar JN218 was conducted to study the effects of applying different concentrations (0, 10, 25 and 50 mg x kg(-1)) of selenium (Se) on the Se allocation in plant organs, grain yield, and its quality. At low concentrations (< or = 10 mg x kg(-1)), Se stimulated maize growth, and increased biomass accumulation and grain yield significantly. At high concentrations (> 25 mg x kg(-1)), Se inhibited maize growth, and decreased dry mass accumulation, grain yield, and its quality.
