title: [Research advances in plant selenium nutrition and its mechanism].
abstract: The amount of selenium in soil environment significantly influences the selenium nutrition of plants. In this paper, the absorption, accumulation and translocation of Se in plants was discussed, and the toxicity of selenium and its effect on crop yield and quality was summarized. The advances in related researches were also introduced. On the basis of these, a new approach on the effect of selenium on soil enzyme activities to elaborate the essentiality of selenium for plants was proposed.
