Unlabelled: Hydrogen peroxide (HO) plays a central role in responses to salt stress, a major abiotic stress that impacts crop yield worldwide. Despite the evidence that HO mitigates salt stress and improves post-harvest quality on several species, its effects on radish were not investigated so far. Thus, the objective of this study was to evaluate the exogenous application of HO on salt stress mitigation of radish growth, physiology, and post-harvest quality.

Article Synopsis
- The study investigates how pre-harvest application of nitric oxide (NO) affects the post-harvest quality of red beet plants grown under normal and drought conditions.
- Drought conditions decreased root yield and certain nutrients in the beets, but the application of sodium nitroprusside (an NO donor) helped reverse these negative effects and improved the overall antioxidant capacity and quality of the beets.
- The findings suggest that treating beets with NO can enhance their quality and resilience against drought, indicating potential benefits for other crops and various stress conditions in future research.
Many biogeochemical processes are modulated by dissolved organic matter (DOM), but the drivers influencing the chemodiversity of DOM compounds in Amazonian soils are poorly understood. It has also been theorized whether deforestation controls the decline of DOM. In this study, we collected soil samples from thirty sites across different regions of Brazil's Legal Amazon, and we investigated the trade-offs among soil physical-chemical properties and DOM chemodiversity.
