Uptake and Translocation of Cesium in Lettuce (Lactuca sativa L.) under Hydroponic Conditions

The uptake of radiocesium (RCs) by plants is key to the assessment its environmental risk. However, transfer process RCs in water-vegetable system still remains unclear. In this work, and accumulation processes Cs+ (0-10 mM) lettuce were explored under different conditions using hydroponics. results showed that higher exposure concentration could lead a faster rate would be beneficial Cs+. K+ roots leaves was inhibited significantly when increased, but unapparent for Ca2+ Mg2+. It found was, inhibition root. leads decrease chlorophyll content brought negative effect on plant photosynthesis, consequently, morphology obvious biomass root length. contents glutathione (GSH), malondialdehyde (MDA), vitality increasing during growth following stress high concentrations Cs+, which caused stresses antioxidant lettuce. enrichment coefficient range 8-217. Moreover, factor 0.114-0.828, suggested enhance from leaf. This study provides more information water food chain, promoting understanding potential risk RCs.
