Climatic variables are the main factors determining the crop productivity, and these undergo changes in the course of time. Though silicon (Si) is not an essential element for the plants, its significant role has been observed in various plant species. Use of silicon could stimulate plant growth and mitigate multiple stresses such as salinity, drought, heat, extreme temperature, metal toxicity and nutritional imbalance as well as the stress linked with changes in global climatic variables. Silicon can also delay leaf senescence. In addition, Si is not harmful to plants even when present in excess. Eco-friendly techniques would be needed for addressing the growing demands for food grains and other agricultural production. The use of Si would become a sustainable strategy for increasing crop yield, improving quality and mitigating abiotic stresses in the near future. This review highlights our current understanding on the use of silicon to mitigate abiotic stresses and enhance crop production.

缓解气候变化以改善甘蔗：硅在缓解非生物胁迫中的作用

气候变量是决定农作物生产力的主要因素，并且这些因素会随着时间的流逝而发生变化。尽管硅不是植物必需的元素，但已在各种植物物种中观察到了其重要作用。硅的使用可以刺激植物生长并减轻多种压力，例如盐度，干旱，高温，极端温度，金属毒性和营养失衡以及与全球气候变量变化有关的压力。硅还可以延迟叶片衰老。另外，即使过量存在，Si也不会对植物有害。将需要生态友好的技术来满足对粮食和其他农业生产不断增长的需求。硅的使用将成为提高作物产量的可持续策略，在不久的将来提高质量并缓解非生物胁迫。这篇评论强调了我们目前对使用硅缓解非生物胁迫和提高农作物产量的理解。
