Silicon (Si) is abundant in the lithosphere, and previous studies have confirmed that silicon plays an important role in plant growth. Higher plants absorb soluble silicon from soil through roots which is deposited in plant tissues mainly in the form of phytoliths. Based on previous studies, the research progress in silicon and phytoliths in the structural protection, enhancement on photosynthesis and transpiration of plants and plant growth and stress resistance was reviewed. Meanwhile, gaps in phytolith research, including phytolith morphology and function, impact of diverse environmental factors coupling with phytoliths, phytolith characteristics at different stages of plant development and phytoliths in regional vegetation are identified. The paper intends to promote the wider application of phytolith research findings and provides reference for further research on phytoliths.
硅（Si）在地壳中含量丰富，已有研究证实硅在植物生长中发挥着重要作用。高等植物通过根系吸收土壤中的可溶性硅，这些硅主要以植硅体的形式沉积在植物组织中。基于前人的研究，本文综述了硅和植硅体在植物结构保护、增强光合作用和蒸腾作用、促进植物生长和提高抗逆性等方面的研究进展。同时，本文还指出了植硅体研究中存在的问题，包括植硅体形态和功能、不同环境因素与植硅体的耦合作用、植物发育不同阶段的植硅体特征以及区域植被中的植硅体等，以期促进植硅体研究成果的广泛应用，并为植硅体的进一步研究提供参考。
