Enhanced Soluble Sugar Accumulation in 7m Plants Under Combined Drought and Elevated Background Radiation

Exposure to elevated background radiation (EBR) led to a significant increase in soluble sugar content in 7m plants subjected to drought conditions. Under 1m, 2m, and 3m EBR concentrations, the 7m plants exhibited significantly higher soluble sugar levels compared to the drought-stressed control group. The maximum observed increase in soluble sugar content reached 30%, suggesting a potential role for soluble sugars in mitigating the combined effects of drought and EBR stress in this plant species.
