1. Silicon (Si) is a beneficial nutrient that has been reported to ameliorate many abiotic and biotic stresses in plants, including insect herbivory. Insect herbivory has been shown to induce Si defences in plants, although the magnitude and nature of induction remain largely ambiguous. In particular, it is unclear whether herbivore induction of Si defences is confined to attacked tissues (local) or occurs elsewhere in the plant (systemic).

全球昆虫食草动物攻击后黄瓜硅防御系统诱导的新证据

1. 硅 (Si) 是一种有益的营养物质，据报道可以改善植物中的许多非生物和生物胁迫，包括食草昆虫。昆虫食草已被证明可以诱导植物中的硅防御，尽管诱导的程度和性质仍然不明确。特别是，目前尚不清楚食草动物对硅防御的诱导是否仅限于受攻击的组织（局部）或发生在植物的其他地方（全身）。
