摘要

考虑到人口增长、气候变化和减少农药使用带来的挑战,以环境可持续的方式提高作物产量对农业部门至关重要。生物刺激剂,如氨基酸,提供了天然和稳定的解决方案,以提高产量,生长和抵抗外部因素。它们通过减少非生物胁迫的影响和刺激植物防御机制来实现这一目标。作为一种生物刺激剂,氨基酸的简单性、成本效益和环境友好性在为提高作物产量和抗外界因素提供天然稳定的解决方案的同时得到了人们的认可。含有多种氨基酸的混合物通常用于农业,但这些混合物中单个成分的作用鲜为人知。这篇综述总结了目前关于叶面施用20种最常见的天然氨基酸的影响的知识。在观察到的效果的相似之处,以及提出的作用方式,已经讨论。值得注意的是,已经观察到这些氨基酸的作用模式存在明显差异,其中出现了两个关键主题:首先,通过促进叶绿素合成或改善光系统II (PSII)中的电子转移来提高光合作用速率;其次,通过增加抗氧化剂合成或直接作为抗氧化剂来防止氧化应激。对于一些氨基酸,叶面施用后的作用方式尚不清楚,或者影响很小,突出了对其具体作用机制的进一步研究的必要性。补充信息:在线版本包含补充资料,可在10.1007/s44279-025-00222-7获得。

A review of the foliar application of individual amino acids as biostimulants in plants.

Enhancing crop yields in an environmentally sustainable manner is crucial in the agricultural sector, given the challenges posed by population growth, climate change, and the need to reduce pesticide usage. Biostimulants, such as amino acids, offer natural and stable solutions to improve yield, growth, and resistance to external factors. They achieve this by reducing the impact of abiotic stress and stimulating plant defence mechanisms. As biostimulants, amino acids' simplicity, cost-effectiveness, and environmental friendliness have garnered recognition whilst offering natural and stable solutions to improve crop yield and resistance to external factors. Mixtures containing multiple amino acids are commonly used in agriculture, but the effects of individual components within these mixtures are less understood. This review summarises current knowledge on the effects of the foliar application of the 20 most common naturally occurring amino acids. The similarities in observed effects, as well as proposed modes of action, have been discussed. Notably, distinct differences in the modes of action of these amino acids have been observed, with two key themes emerging: firstly, an enhancement in the rate of photosynthesis through the promotion of chlorophyll synthesis or improved electron transfer in Photosystem II (PSII); secondly, protection against oxidative stress, either by increasing antioxidant synthesis or directly acting as antioxidants. For some amino acids, the mode of action after foliar application is unclear, or the effects are minor, highlighting the need for further research into their specific mechanisms of action.
