盐度是一种非生物胁迫，通过严重影响作物生长和最终产量来影响农业。考虑到海平面以每年30毫米的惊人速度上升，很明显，盐胁迫对农业构成了最大的威胁。在对高盐敏感的重要经济作物中，番茄（Solanum lycopersicum L.）比其野生品种更容易受到盐胁迫的影响。文献中有大量证据证明了准必需类金属硅（Si）的有益作用，它可以增加植物的活力并保护植物免受(A)生物胁迫。这种保护是通过在细胞壁中沉淀为乳白色二氧化硅来实现的，这构成了植物病原体进入的机械屏障。就硅积累而言，番茄被归类为非积累者（排除者），类似于茄科的其他成员，如烟草。尽管积累Si的能力较低，但当提供给番茄植株时，金属样物质在(a)生物胁迫条件下改善生长，例如，通过提高果实产量或通过调节生理参数改善营养生长。鉴于硅在作物保护中的益处，本文从其作为生物刺激素、促进果实产量及其收获后稳定性的角度，综述了硅在缓解番茄盐胁迫方面的现有文献数据。
Salinity is an abiotic stress that affects agriculture by severely impacting crop growth and, consequently, final yield. Considering that sea levels rise at an alarming rate of >3 mm per year, it is clear that salt stress constitutes a top-ranking threat to agriculture. Among the economically important crops that are sensitive to high salinity is tomato (Solanum lycopersicum L.), a cultivar that is more affected by salt stress than its wild counterparts. A strong body of evidence in the literature has proven the beneficial role of the quasi-essential metalloid silicon (Si), which increases the vigor and protects plants against (a)biotic stresses. This protection is realized by precipitating in the cell walls as opaline silica that constitutes a mechanical barrier to the entry of phytopathogens. With respect to Si accumulation, tomato is classified as a non-accumulator (an excluder), similarly to other members of the nightshade family, such as tobacco. Despite the low capacity of accumulating Si, when supplied to tomato plants, the metalloid improves growth under (a)biotic stress conditions, e.g., by enhancing the yield of fruits or by improving vegetative growth through the modulation of physiological parameters. In light of the benefits of Si in crop protection, the available literature data on the effects of this metalloid in mitigating salt stress in tomato are reviewed with a perspective on its use as a biostimulant, boosting the production of fruits as well as their post-harvest stability.
