Title
Common reed absorbs K+ more selectively than rice against high Na+/K+ ratio in nutrient solution

Other claims from this paper (6)
- Observation Under excess sodium, common reed maintained constant potassium content in all plant parts.
- Association Under excess sodium, rice potassium content decreased as sodium concentration increased.
- Observation Preferential potassium uptake at high Na+/K+ was approximately tenfold greater in common reed than rice.
- Observation Excess sodium had a small impact on net potassium absorption in common reed.
- Intervention effect Excess sodium decreased net potassium absorption rate in rice.
- Mechanism The authors propose that root potassium transporter or channel selectivity could explain potassium accumulation differences between rice and common reed.
