Barringtonia racemosa is a typical and endangered semi-mangrove, which may be suffering from heavy Pb pollution. Jasmonic acid (JA) can regulate plant defense mechanisms under Pb stress. This study explored the defense and adaptive mechanisms of B. racemosa under the regulation of JA through controlled experiments with a Pb concentration gradient. Results showed that exogenous JA significantly increased the palisade tissue and root cortex thickness of B. racemosa under different Pb concentrations, while the thickness of the vascular bundle diameter had the opposite response. Peroxidase activity, proline and chlorophyll concentrations were significantly increased under Pb stress. It can be concluded that increasing palisade tissue thickness, concentrations of photosynthetic pigments and antioxidant enzymes are aided by JA and constitute a vital Pb-stress response strategy for B. racemosa. JA enhanced antioxidant defense mechanisms, mitigating Pb toxicity and reducing reactive oxygen species produced under heavy Pb stress. Remarkably, under high Pb concentration, the bioconcentration factor and Pb absorption of B. racemosa were significantly reduced, improving its tolerance to Pb stress.

The results revealed that cobalt contamination had a negative impact on plant growth, reducing chlorophyll and carotenoid content, increasing oxidative stress, and elevating cobalt accumulation in the shoot while also decreasing nutrient content.
