Boron (B), an essential nutrient for plants, participates in many physiological processes, with emphasis its role in the formation of the plant's cell wall. In soil, the range between deficiency and toxicity of B is very narrow as compared to other nutrients, which makes its management in agriculture very difficult, as it depends on the soil and environmental conditions. B stress simultaneously acts with others (extreme temperatures, excess of light, high concentration of CO2, drought, salinity or heavy metal contamination, etc.). The effects of these other stresses could increase the sensitivity of plants to B toxicity or deficiency. The simultaneous combination (B stress × other abiotic stresses) is a complex interaction that should be analyzed in detail if the resistance of crops to climate change is needed. This article reviews the response of plants when facing a combination of B stress with other stresses, and compares this response with the individual stresses. Also, in the last few years, the role of B has been described in multiple plant functions that can improve its resilience to specific stresses. Thus, this article also analyses in what conditions the application of B can be efficient for the improvement of the plant's response to other stresses.

植物发生硼胁迫和缺乏时会产生多重胁迫。

硼(B)是植物必需的营养素,它参与许多生理过程,尤其是硼在植物细胞壁形成中的作用。在土壤中,与其他养分相比,硼的缺乏和毒性之间的范围非常狭窄,这使其在农业中的管理非常困难,因为它取决于土壤和环境条件。B应力与其他应力同时作用(极端温度,光线过剩,高浓度的CO2,干旱,盐度或重金属污染等)。这些其他胁迫的影响可能会增加植物对B毒性或缺乏的敏感性。同时组合(B胁迫×其他非生物胁迫)是一个复杂的相互作用,如果需要农作物对气候变化的抵抗力,则应进行详细分析。本文回顾了植物面临B胁迫与其他胁迫的组合时的响应,并将该响应与单个胁迫进行比较。另外,在最近几年中,已经描述了B在多种植物功能中的作用,可以提高B对特定压力的适应性。因此,本文还分析了在何种条件下施用B可以有效改善植物对其他胁迫的反应。
