摘要
氧化应激源于活性氧(ROS)的产生和积累之间的不平衡,它会阻碍植物在各种环境压力下的生长。虽然水涝是众所周知的氧化应激诱导因素,但氧化应激对使用深流技术(DFT)水培系统种植的植物根系的影响仍然知之甚少。在这项研究中,我们证明了 N-乙酰半胱氨酸(NAC)能促进移植到深流技术水培系统中的莴苣幼苗的生长。施用 NAC 能明显改善芽和根的生长,浓度为 0.3 mM 时效果最明显。此外,NAC 还能减轻移植后根部过氧化氢的积累。它还能减少根和芽中脂质过氧化和总酚含量的暂时增加。这些结果表明,NAC 可作为一种抗氧化剂,通过清除根中的过氧化氢来减轻氧化应激。重要的是,NAC 的保护作用可能会扩展到其他水培作物,从而为各种栽培系统提供更广泛的减少氧化应激的潜力。
N-Acetylcysteine Mitigates Oxidative Stress Induced by Transplanting Lettuce Seedlings into a DFT Hydroponic System
Oxidative stress results from an imbalance between the production and accumulation of reactive oxygen species (ROS), which can impede plant growth under various environmental stresses. While waterlogging is a well-known inducer of oxidative stress, the effects of oxidative stress on plant roots grown using the deep flow technique (DFT) hydroponic system remain poorly understood. In this study, we demonstrate that N-acetylcysteine (NAC) enhances the growth of lettuce seedlings transplanted into a DFT system. NAC application significantly improved both shoot and root growth, with the most pronounced effects observed at a concentration of 0.3 mM. Moreover, NAC mitigated the accumulation of hydrogen peroxide in roots following transplantation. It also reduced a temporary increase in lipid peroxidation and total phenolic content in both roots and shoots. These results suggest that NAC functions as an antioxidant, alleviating oxidative stress by scavenging hydrogen peroxide in the roots. Importantly, NAC’s protective effects may extend to other hydroponically grown crops, offering broader potential for reducing oxidative stress across various cultivation systems.
