- Intervention effect Silicon did not affect growth under control conditions.
- Intervention effect Potassium deficiency reduced growth and water status.
- Intervention effect Silicon alleviated potassium deficiency reductions in growth and water status.
- Intervention effect Silicon moderated potassium deficiency reductions in gas exchange and conductance.
- Intervention effect HgCl2 treatment eliminated 29% of silicon alleviated transpiration.
- Mechanism Authors infer aquaporin was not the primary cause of hydraulic reversal.
- Intervention effect Silicon significantly increased xylem sap potassium concentration.
- Intervention effect Silicon decreased xylem sap osmotic potential.
- Mechanism Authors attribute improved conductance to potassium accumulation increasing osmotic gradient.
