Learn how Citrus grandis stress tolerance can be enhanced by raising soil pH to reduce oxidative stress caused by manganese toxicity.
Citrus grandis Stress Tolerance: Role of Antioxidant Systems in Manganese Toxicity
The study found that raising the growth medium’s pH from 3 to 5 significantly enhanced Citrus grandis stress tolerance, enabling seedlings to better resist oxidative stress caused by excessive manganese (Mn), a common problem in acidic soils. Higher pH levels reduced the accumulation of reactive oxygen species (ROS), methylglyoxal (MG), and malondialdehyde (MDA)—key markers of oxidative damage—in both roots and leaves, further strengthening Citrus grandis stress tolerance.
Additionally, it improved the coordinated activity of detoxification systems that neutralize ROS and MG under high Mn stress, highlighting how soil pH adjustment supports overall Citrus grandis stress tolerance. These results suggest that increasing pH not only reduces oxidative injury but also provides a practical approach to managing manganese toxicity while maintaining healthy growth, demonstrating the critical role of Citrus grandis stress tolerance in resilient citrus cultivation.
Rong‑Yu Rao, Fei Lu, Bin‑Bin Lan, Xian Zhu, Wei‑Lin Huang, Xu‑Feng Chen, Ning‑Wei Lai, Lin‑Tong Yang, Jiuxin Guo, and Li‑Song Chen conducted the study and published it under the title “Augmenting pH Confers to Citrus grandis the Ability to Combat Oxidative Stress Triggered by Manganese Excess” in January 2026.

Practical usage day to day life
The study shows that, as a result of higher soil pH, Citrus grandis stress tolerance is significantly improved, enabling the plants to better combat manganese-induced stress. In addition to this, gardeners can use these findings in both home gardens and commercial citrus farms to enhance overall Citrus grandis stress tolerance. For instance, adding lime or other natural alkaline materials to soils with high acidity effectively raises pH, which further strengthens Citrus grandis stress tolerance. Consequently, manganese toxicity is reduced, and the plants remain healthier over time, reflecting the enhanced resilience provided by improved Citrus grandis stress tolerance.
As a result of this practice, Citrus grandis stress tolerance is enhanced, reducing oxidative stress and allowing for strong growth. In addition, leaves remain vibrant, and fruit yield improves, further reflecting improved Citrus grandis stress tolerance. For example, these techniques can be applied in pots or backyard orchards. At the same time, gardeners should monitor soil pH and gradually raise it. By doing so, the plants’ natural detoxification systems are strengthened, boosting overall Citrus grandis stress tolerance and enabling them to handle environmental and manganese-induced stress more effectively.
