- •
Gas exchange, plant water status and radiation use efficiency of giant reed were studied.
- •
Soil water content and nitrogen fertilization significantly increased the studied parameters.
- •
High radiation use efficiencies and low light extinction coefficients were found.
- •
Stomata regulation might explain the drought tolerance of giant reed.
- •
The instantaneous water use efficiency was improved at mild soil water availability.
