| Abstract: |
|
| Keywords: | eutrophication free amino acid dosing soluble carbohydrate submersed macrophytes |
dosing changed C‐N metabolism significantly by decreasing the soluble carbohydrate (SC) content and increasing the 
‐N and free amino acid (FAA) content of plant tissues. 
dosing were closely correlated (positive for SC and negative for FAA) with the colonising water depths of the plants in Lake Erhai, the plants adapted to lower light regimes being more efficient in maintaining SC and FAA homeostasis.
