AI Technical Summary
Technical Problem
Bermuda grass has limited salt tolerance under salt stress. Traditional improvement methods are costly and difficult to apply on a large scale. There is an urgent need for green, rapid and replicable methods to improve salt tolerance.
Method used
Exogenous application of 3-N-methyl-L-histidine (MH) regulates the physiological response of bermudagrass, reduces salt stress-induced oxidative damage, and enhances its adaptability to high-salt environments.
Benefits of technology
By applying MH exogenously, the degree of oxidative stress, membrane lipid peroxidation level and content of osmotic regulator Pro are significantly reduced, osmotic balance is maintained and the growth capacity of Cynodon dactylon in high-salt environments is enhanced.

Abstract
本发明属于植物抗逆调控技术领域，具体涉及一种3‑N‑甲基‑L‑组氨酸在提高狗牙根盐胁迫耐受性中的应用。本研究证实，于盐胁迫发生前和 / 或盐胁迫持续阶段，对狗牙根外源施用3‑N‑甲基‑L‑组氨酸，可显著降低植株过氧化氢（H2O2）积累水平与丙二醛（MDA）表征的膜脂过氧化程度，并下调渗透调节物质脯氨酸的累积，有效减轻盐胁迫对狗牙根造成的生理损伤，显著改善植株在高盐环境下的生长适应性。该调控方法操作简便易行，适用于盐碱地植被修复与生态绿化建植工程，产业化应用前景广阔。
