植物硒素营养及其机理研究进展

Research advances in plant selenium nutrition and its mechnism.

土壤生境中Se的丰缺对植物的Se素营养有重要的影响 .本文阐述了植物对Se的吸收、积累和运移过程 ,概述了Se对植物的毒性、对植物产量和品质影响及其机理研究的进展 .在此基础上 ,提出以研究Se对土壤酶活性影响来解释Se对植物的必要性的新途径 .

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.
