硒增强植物抗逆能力及其机理研究进展

硒是植物有益元素之一，已被证实能够增强植物抗逆能力。为准确把握硒增强植物抗多种逆境能力的研究动态，分别检索、分析了国内外关于硒增强植物抵抗重金属污染、病虫害、盐害、干旱、高低温等逆境的研究进展；讨论植物抗逆能力形成与硒营养的关系。总结、提出硒增强植物抗病虫害和干旱胁迫能力的研究需要加强；硒增强植物抵御重金属胁迫的机理研究需要深入。为推进硒增强植物抗逆能力的研究和促进硒在环境污染、农业安全生产等领域的应用提供依据和借鉴。

Progress of Selenium Enhance Plant Resilience and Its Mechanisms

Selenium is one of the beneficial elements of plant, which has also been confirmed as one of the trace elements to enhance the resilience of plants. To introduce both foreign and domestic research state of application with selenium on plant to enhanced resilience against various stress, it has retrieved reports that about the relationship between selenium and the biological function of adversity stress containing heavy metal, plant diseases and insect pests, salt stress, drought, high temperature or freezing stress. Here, the research progress of the role selenium plays on every adversity conditions was summarized and discussed based on the statistical analysis of the research on the relationship between the resistance ability of selenium and plant. Pointing out that research of selenium enhancing resilience on plants, under the pests and drought stress, need to be strengthened. Further more study should focus on the mechanism of selenium improving plant against heavy metal stress. The purpose was to provide theoretical basis for the promotion of selenium that used in the field of environmental pollution, agricultural production safety and so on.
