随着全球人口的增加，对粮食作物、油料、纤维和其他副产品的需求不断增加。与这种日益增长的需求相反，非生物胁迫阻碍了植物的生产力。非生物胁迫有时会减少一半以上的作物产量。为了实现全球粮食安全，了解植物对非生物胁迫的反应是至关重要的，因为这是开发提高植物胁迫耐受性的方法/工具的先决条件。微量元素是促进一系列生理功能所需的少量营养素。这些因素刺激增长，但不是必需的。有些是只对某些植物物种或在特定条件下所必需的。微量元素不仅能促进植物的生理过程和生长发育，而且在提高植物的抗逆性方面也发挥着重要作用。然而，微量元素在赋予植物非生物胁迫耐受性方面的实际生理功能仍有待研究。本章重点介绍了微量元素的作用，特别是生物微量元素在植物非生物胁迫耐受性中的作用。
With the increase of global population, the demand for food crops, oil, fiber and other by-product yielding crops is increasing. In contrast to this increasing demand, abiotic stresses hinder the productivity of plants. Abiotic stresses sometimes reduce more than half of the crop yields. To attain global food security, understanding of plant responses to abiotic stresses is crucial because this is the prerequisite for developing approaches/tools for improving plant stress tolerance. Trace elements are nutrients required in small quantities to facilitate a range of physiological functions. These elements stimulate growth but are not essential. Some are essential only for certain plant species or required under a given condition. Trace elements not only improve plant physiological processes and growth but play roles in improving plant stress tolerance. However, the actual physiological functions of trace elements in conferring abiotic stress tolerance are still under study. This chapter focuses on the roles of trace elements emphasizing especially the recent advances on the actions of biological trace elements in plant abiotic stress tolerance.
