Biostimulants (BSs) are probably one of the most promising alternatives nowadays to cope with yield losses caused by plant stress, which are intensified by climate change. Biostimulants comprise many different compounds with positive effects on plants, excluding pesticides and chemical fertilisers. Usually mixtures such as lixiviates from proteins or algal extracts have been used, but currently companies are interested in more specific compounds that are capable of increasing tolerance against abiotic stress. Individual application of a pure active compound offers researchers the opportunity to better standarise formulations, learn more about the plant defence process itself and assist the agrochemical industry in the development of new products. This review attempts to summarise the state of the art regarding various families of organic compounds and their mode/mechanism of action as BSs, and how they can help maximise agricultural yields under stress conditions aggravated by climate change.
生物刺激素（BSs）可能是目前应对因植物胁迫导致的产量损失最有前景的替代方法之一，而气候变化加剧了这种胁迫。生物刺激素包含许多对植物有积极作用的不同化合物，但不包括农药和化肥。通常使用的是诸如蛋白质浸出液或藻类提取物之类的混合物，但目前企业对能够提高植物对非生物胁迫耐受性的更特定化合物感兴趣。单独施用一种纯活性化合物为研究人员提供了更好地标准化配方、更多了解植物防御过程本身以及协助农用化学品行业开发新产品的机会。本综述试图总结关于作为生物刺激素的各类有机化合物及其作用方式/机制的最新研究状况，以及它们如何有助于在气候变化加剧的胁迫条件下实现农业产量最大化。
