Abstract

Silicon (Si) has emerged as a pivotal element influencing various aspects of plant growth and development. This review explores the multifaceted effects of Si on plants, encompassing both biotic and abiotic dimensions. Si, primarily absorbed by plants in the form of orthosilicic acid, demonstrates a diverse range of roles in enhancing plant resistance to environmental stresses. Biotic stresses, including pathogen attacks and insect infestations, are notably mitigated by the deposition of Si in plant tissues, fortifying cell walls and triggering defence mechanisms. Furthermore, Si plays a crucial role in alleviating abiotic stresses such as drought, salinity and metal toxicity, imparting resilience to plants in challenging environments. The interaction between Si and plant physiology involves intricate mechanisms, impacting nutrient uptake, photosynthesis and hormonal regulation. As research in this field advances, a comprehensive understanding of the nuanced effects of Si on plants emerges, paving the way for innovative agricultural practices and the development of stress-resistant crop varieties. This review delves into the contemporary knowledge surrounding the effects of Si on plants, underscoring its significance in promoting plant resilience and sustainable agriculture.

硅,减轻(A)生物压力对作物影响的新兴战略:综述
硅(Si)已成为影响植物生长和发育各个方面的关键元素。本综述探讨了硅对植物的多方面影响,包括生物和非生物两方面。硅主要以正硅酸的形式被植物吸收,在增强植物对环境胁迫的抵抗力方面发挥着多种作用。硅在植物组织中的沉积、细胞壁的加固和防御机制的触发,明显减轻了包括病原体侵袭和虫害在内的生物胁迫。此外,硅还在缓解干旱、盐碱和金属毒性等非生物胁迫方面发挥着重要作用,赋予植物在挑战性环境中的恢复能力。硅与植物生理之间的相互作用涉及复杂的机制,对养分吸收、光合作用和激素调节都有影响。随着这一领域研究的深入,人们开始全面了解硅对植物的微妙影响,为创新农业实践和抗逆作物品种的开发铺平了道路。本综述深入探讨了有关硅对植物影响的当代知识,强调了硅在促进植物抗逆性和可持续农业方面的重要意义。

期刊介绍: The effects of stress on crop production of agricultural cultivated plants will grow to paramount importance in the 21st century, and the Journal of Agronomy and Crop Science aims to assist in understanding these challenges. In this context, stress refers to extreme conditions under which crops and forages grow. The journal publishes original papers and reviews on the general and special science of abiotic plant stress. Specific topics include: drought, including water-use efficiency, such as salinity, alkaline and acidic stress, extreme temperatures since heat, cold and chilling stress limit the cultivation of crops, flooding and oxidative stress, and means of restricting them. Special attention is on research which have the topic of narrowing the yield gap. The Journal will give preference to field research and studies on plant stress highlighting these subsections. Particular regard is given to application-oriented basic research and applied research. The application of the scientific principles of agricultural crop experimentation is an essential prerequisite for the publication. Studies based on field experiments must show that they have been repeated (at least three times) on the same organism or have been conducted on several different varieties.
